In the circuit shown in fig. 14.25- Would any of the bulb glow when the switch is in the 'OFF' position?

In the circuit shown in Fig. EP 14.40, find the value of R_c .

When does a bulb glow ?

Zubeda made n electric circuit using a cell holder shown in fig.14.4, a switch and a bulb. When she put the switch in the 'ON' position, the bulb did not glow. Help zubeda in identifying the possible defects in the circuit.

For the circuits shown in figure I and II the voltmeter reading would be

In the circuit shown, when galvanometer G shows no deflection, the current in the 2 ohm resistor is

In the circuit shown in Fig. EP. 14.7, if the diode forward voltage drop is 0.3 V, the voltage differnece between A and B is
