1. Two cells E1 and E2, having e.m.f. 4 V and 8 V and internal resistance 0.5 Ω and 1 Ω respectively are connected as shown. Find the current in each resistor and potential difference across each cell.
2. A galvanometer having 30 divisions has a current sensitivity of 20 μA per division and a resistance of 25 ohm. Find the shunt required to convert it into an ammeter of 1 ampere range. Find the resistance which should be connected in series to convert this ammeter into a voltmeter of range 1 V.
3. A heater is designed to operate with a power of 1000 watts in a 100-volts line. It is connected, in combination with a resistance of 10 ohms and a resistance R, to a 100-volts mains as shown in the figure. What should be the value of R so that the heater operates with a power of 62.5 watts?
4. In the circuit shown a voltmeter reads 30 volts when it is connected across the 400 ohms resistance. Calculate what the same voltmeter will read when it is connected across the 300 ohm resistance ?
5. A galvanometer of unknown resistance in series is connected across two identical cells each of 1.5 volt. When the cells are connected in series, the galvanometer records a current of 1 A and when the cells are in parallel, the current is 0.6 A. Find the internal resistance of the cell.
6. Determine the charge and energy stored in the capacitor in the figure for the circuit in which internal resistance of battery, r = 4Ω. Also, find the value of r for which the charge on the capacitor is zero.
