Question : The potential difference across the wire having fixed resistance is tripled. By how much does the electric power increase?
Answer :  The electric power will increase by nine times when the potential difference across the wire having fixed resistance is tripled. According to Ohm’s law, potential difference V is proportional to current, I. Therefore, when V is made 3 times, I will increase 3 times. As Power P = VI, therefore, Power will increase by 9 times.

Question : find the minimum rating of fuse that can be safely used on a line on which two 1.1 KW electric geysers are to run simultaneously.
The supply voltage is 220 V.
Answer :  Power P = VI. As the two geysers have power rating 1.1 kW or 1100 W and are connected in parallel, each geyser draws a current I = P/V = 1100/220 A = 5 A.

Question : Should the resistance of an ammeter be low or high? Give reason. 
Answer :  An ideal ammeter is one which has zero resistance. But that is not possible. Therefore, the resistance of an ammeter should be as close to zero as possible. If it is non-zero and
substantial, it will affect the current flowing through the circuit. This is because an ammeter is connected in series in the circuit for the measurement of electric current.

Question. Derive the relation 1/R = 1/R1 + 1/R2 + 1/R3 when resistors are joined in parallel.
Answer: In parallel combination of three resistance R1, R2 and R3, the current in each of the resistance is different. If I is the current drawn from the cell then it is divided into branches as I1, I2 and I3. Thus,
I = I1 + I2 + I3
The potential difference across each of these resistances is the same.
Thus, from Ohm’s law
I1 = V /R1 , I2 = V/R2 , I3 = V/R3
If R is the equivalent resistance then,

Question : Heat is generated continuously in an electric heater, but the temperature of its element becomes constant after some time. Why? 
Answer :   When the temperature of the heater becomes greater than the temperature of the surroundings, some of the heat is lost to the surroundings in the form of thermal radiations and through convection. After some time,the rate at which heat is being produced becomes equal to the rate of which heat is lost. Hence, the temperature of the element becomes constant. This happens because an equilibrium or steady state is reached.

Long Answers :

Question :  a. Define electrical energy with the S.I. unit?
b. A household uses the following electric appliance:
(i) Refrigerator of rating 400Wfor ten hours each day.
(ii) Two electric fans of rating 80W each for twelve hours each day.
(iii) Six electric tubes of rating 18W each for six hours each day.
Calculate the electricity bill of the household for the month of June if the cost per unit of electric energy is Rs.3.00
Answer : 
a. The work done by a source of electricity to maintain current in a circuit is known as electrical energy. Its S.I. unit is joule.

b. i. Electricity consumed by refrigerator in one day

= power x time

= 400W x 10h

= 4000Wh

= 4kWh

ii. Electricity consumed by 2 electric fans in 1 day

= power x time

= 2 x 80W x 12h

= 1920Wh

= 1.92kWh

iii. Electricity consumed by 6 electric tubes in 1 day

= 6 x 18W x 6h

= 648wh = 0.648 kWh

Total energy consumed in one day

= 4+1.92+0.648 = 6.548 kWh

Total energy consumed in one month

= 6.568 x 30

= 197.04 kWh

Cost of 1 unit (kWh) = Rs. 3.00

Cost of 197.04 kWh = 197.04 3

The required electricity bill = Rs. 591.12

Question. How can three resistors of resistances 2 W, 3 W and 6 W be connected to give a total resistance of (a) 4 W and (b) 1 W?
Answer: (a) The three resistors of resistances 2 W, 3 W and 6 W have to be combined as shown in the figure to obtain 4 W resistance.
Equivalent resistance of 3 W and 6 W connected in parallel is, 1/Rp = 1/3 + 1/6 = 2 + 1/6 = 3/6
or RP = 6/3 = 2 W 126
Now, RP and 2 W are joined in series and the equivalent resistance is,
R = RP + 2
= (2 + 2) W
= 4 W
(b) In order to obtain 1 W resistance, the resistors 2 W, 3 W and 6 W have to be combined as shown in figure.
2 W, 3 W and 6 W resistances are connected in parallel, 126
∴ 1/R = 1/2 + 1/3 + 1/6
= 3 + 2 + 1/6
= 6/6
or R = 1 W

Question. How many 176 W resistors in parallel are required to carry 5 A on a 220 V line?
Answer: Here, Potential difference, V = 220 V, Current, I = 5 A
∴ Resistance, R = V/I
= 220/5 = 44 W
Let the number of 176 W resistors to be connected in parallel to give an equivalent resistance of 44 W be x.
Equivalent resistance of ‘x’ 176 W resistance connected in parallel is 176/x W
But, 176/x , = 44
∴ x = 176/44 = 4
Thus, 4 resistors of 176 W each should be connected in parallel.

Question. Draw a schematic diagram of a circuit consisting of a battery of three cells of 2 V each, a 5 Ω resistor, an 8 Ω resistor, and a 12 Ω resistor and a plug key, all connected in series. Now, connect the ammeter to measure the current through the resistors and a voltmeter to measure the potential difference across the 12 Ω resistors. What would be the readings in the ammeter and the voltmeter?
Answer: The total resistance of the circuit is given by
R = 5 + 8 + 12
= 25 W
We know, R = V/I
Hence, 25 = 6/1
I = 6/25
= 0.24 A
Since, resistances are connected in series, thus electric current
remains the same through all resistors.
Here we have,
Electric current, I = 0.24 A
Resistance, R = 12 Ω
Thus, potential difference (V) through the resistor of 12 Ω is given by
V = I × R
= 0.24 × 12
= 2.88 V
∴ Reading of ammeter = 0.24 A
Reading of voltmeter through resistor of 12 Ω = 2.88 V.

Question. In the circuit given below, calculate the value of x, if the equivalent resistance between the points A and B is 6 W. 
CBSE Class 10 Science Electricity Worksheet
Answer: The network of resistors can be simplified as (·.· 5 W and 7 W are in series and also 8 W and x W are in series).
Here, equivalent resistance (R) = 6 W, R1 = 12 W, R2 = (8 + x) W
The resistors R1 and R2 are connected in parallel.
∴ 1/R = 1/R1 + 1/R2
or 1/6 = 1/12 + 1/8 + x
or 1/6 - 1/12 = 1/8 + x
or 2 - 1/ 12 = 1/8 + x
or 1/12 = 1/8 + x
or 8 + x = 12
∴ x = 12 – 8 = 4 W.

Question. Calculate the equivalent resistance of the following network :
Answer: Let Rp is the equivalent resistance of resistors connected in parallel.
∴ Equivalent resistance of the circuit
1/Rp = 1/20 + 1/20
1/Rp = 1 + 1/20
= 2/20 = 1/10
Rp = 10 W
Now, equivalent circuit becomes.
˙.˙ 10 W and 10 W are connected in series.
∴ Equivalent resistance of the circuit R = 10 W + 10 W
= 20 W

Question. The circuit diagram given below shows the combination of three resistors, R1 = 2 W, R2 = 12 W and R3 = 6 W :
Calculate :
(a) Total resistance of the circuit.
(b) Total current flowing in the circuit.
(c) The potential difference across R1.
(d) The potential difference across R2 or R3.
(e) Current flowing through R2.
Answer: (a) R2 and R3 are in parallel.
∴ Equivalent resistance of R2 and R3
RP = R2 x R3/R2 + R3
= 12 x 6/ 12 + 6 Ω
= 72/18 Ω
= 4 W.
∴ Total resistance of the circuit, R = R1 + RP
Now, R1 and RP are connected in series
= (2 + 4) W
= 6 W
(b) Potential difference, V = 12 V
Total resistance, R = 6 W
Using Ohm’s law,
Total current flowing in circuit,
I = V/R
= 12/6 A = 2A
(c) Potential difference across R1,
V1 = IR1
= 2 × 2 = 4 V
(d) Potential difference across R2 or R3,
V2 = IRP
= 2 × 4 = 8 V
(e) Let the current flowing through R2 be I'.
∴ V2 = I'R2
or I' = V2/R2 = 8/12 A
= 0.67 A.

Question. In a network of resistors as shown in figure, calculate the equivalent resistance between the points (a) S and R and (b) P and R. 
CBSE Class 10 Science Electricity Assignment Set B

Answer: (a) Between S and R : Between the points S and R the above network of resistors can be represented as :
Equivalent resistance of three 3 Ω resistors connected in series,
R1 = (3 + 3 + 3) = 9 Ω
Now, R1 and 3 Ω are connected in parallel.
∴ Equivalent resistance R can be calculated as
1/R = 1/9 + 1/3
= 1 + 3/9
= 4/9
or R = 4/9 Ω = 2.25 Ω
(b) Between P and R : Between the points P and R the network
of resistors can be represented as :
Equivalent resistance of two 3 Ω resistors connected in series is
(3 + 3) = 6 Ω
Now, two 6 Ω resistors are connected in parallel.
∴ Equivalent resistance is given by
1/R = 1/6 + 1/6
1/R = 1+ 1/6 = 2/6 = 1/3
= 3 W.

Question. A copper wire has diameter 0.5 mm and resistivity of 1.6 × 10–8 W m. What will be the length of this wire to make its resistance 10 W ? How much does the resistance change if the diameter is doubled ?
Answer: Here, diameter of wire = 0.5 mm, Resistivity (r ) = 1.6 × 10–8
W M, Resistance (R) = 1 W. Let the length of wire l and the
resistance when diameter is doubled be R1.
∴ Radius = 0.5mn/2 = 0.25 mm
= 0.25/1000 = 0.00025 m
We know that, R = p ,1/A
∴ l = RA/P = Rπr2/p
⇒ l = 10 x 3.14 x (0.00025)2/1.6 x 10 -8
l = 10 x 3.14 x 0.00025 x 0.00025/1.6 x 10 -8
⇒ l = 10 x 3.14 x 0.00000625 x 10 -8/1.6
l = 10 x 10-8 x 0.00000196250/1.6
= 196.26/1.6 = 122.65 m = 122.7 m
When diameter wire is doubled then,
Now diameter = 0.5 × 2 = 1 mm
∴ Radius = 1/2 mn = 0.5 mm
= 0.5 /1000m = 0.0005 m
∴ R1 = p , 1/A = P 1/πr2
= 1.6 ×10–8 × 122.7/3.14 x 0.0005 x 0.0005
= 1.6 ×10–8 x 122.7/3.14 x 0.000000 = 1.6 x 122.7/3.14 x 0.000000 x 10–8
= 196. 32/78.5 = 2.5 W

Question. Which uses more energy, a 250 W T.V. set in 1 hour or a 1200 W toaster in 10 minutes?
Answer: For T.V. Set : Power, P = 250 W
Time, t = 1 h
Electrical energy consumed = P × t
= 250 x 1/1000 kWh
= 0.25 kWh
For toaster : Power, P = 1200 W
Time, t = 10 minutes
= 10/60 h = 1/6 h
Electrical energy consumed = P × t
= 1200 x 1/1000 x 6 kWh
= 0.20 kWh
The T.V. set uses more energy (0.25 kWh) whereas the toaster uses less energy (0.20 kWh).

Question. When a 12 V battery is connected across an unknown resistor, there is a current of 2.5 mA in the circuit. Find the value of the resistance of the resistor.
Answer: Here, Potential difference, V = 12 V
Current, I = 2.5 mA = 2.5/1000 A = 0.0025 A
Using Ohm's law
Resistance, R = V/I = 12/0.0025 = 4800 W

Question : B1 B2 and B3 are three identical bulbs connected as shown in figure. When all the three bulbs glow, a current of 3A is recorded by the ammeter A.

Answer :

 Electricity_8

(i) What happens to the glow of the other two bulbs when the bulb B1 gets fused?
(ii) What happens to the reading of A1, A2, A3 and A when the bulb gets fused?
(iii) How much power is dissipated in the circuit when all the three bulbs glow together?
(i) Since B1, B2 and B3 are in parallel, the potential difference across each of them will remain same. So when the bulb B1 gets fused,B1 ,B2 and B3 have the same potential and continues with the same energy dissipated per second, i.e. they will glow continuously as they were glowing before.
(ii) Resistance of the parallel combination when all the three bulbs are glowing

 Electricity_9

Since resistance of each arm is same and p.d. is also same, current divides them equally. So 1A current will pass through each bulb Bl and By 
Therefore, ammeter A1 and A3 reads l A current while A2 will read zero and ammeter A read 2 A current.
(iii) In parallel, total power consumed
Peq=P1 +P2 +P3
So, when all the three bulbs glow together
