(a) Complete the circuit given in figure by inserting between the terminals A and C, an ammeter. (b) In the diagram mark the polarity at the terminals of ammeter and indicate clearly the direction of flow of current in the circuit, when the circuit is complete. (c) Name and state the purpose of Rh in the circuit.

A charge 0.5 C passes through a cross section of a conductor in 5 s. Find the current.

When starter motor of a car is switched on for 0.8 s, a charge 24 C passes through the coil of the motor. Calculate the current in the coil.

In the given figure, the flow of electrons would be :

1. B to A
2. A to B
3. both A to B and B to A
4. none of the above
