Ex. 1 In the circuit shown below fig. if the resistance of voltmeter is 4KΩ, then the error in the reading of voltmeter will be-
Ex. 2 When a Laclanche cell is connected to a 10Ω resistance then a current of 0.25 ampere flows in the circuit. If the resistance is reduced to 4Ω then current becomes 0.5 ampere. The internal resistance of galvanometer will be-
(A) 1.5 ohm (B) 0.5 ohm (C) 1 ohm (D) 2 ohm
Ex. 3 The emf E and internal resistance r of the cell shown in fig. are 4.3 V and 1 ohm respectively. The resistances of ammeter A and voltmeter V are 2Ω and 200Ω
respectively. Then, the readings in the ammeter and voltmeter are-
Ex. 4 The voltmeter shown in fig, reads 6V across the 60Ω resistor. Then the resistance of the voltmeter is-
Ex. 5 If only one hundredth part of total current flowing in the circuit is to be passed through a galvanometer of resistance GΩ, Then the value of shunt resistance required will be-
(A) G/10 (B) G/100 (C) G/99 (D) G/999
Ex. 8 In the calibration of ammeter experiment, a standard cell of e.m.f. 1.1 volt gets balanced at 7.70 m of potentiometer wire. If the potential difference across 1Ω resistance gets balanced at 1.75m, then the current indicated by ammeter is 2/10A. The error in the reading of ammeter will be-
(A) 0.05 A (B) – 0.05 A (C) zero (D) 0.01 A
