Explain why does a metal wire when connected to a cell offer resistance to the flow of current.

State three factors on which the resistance of a wire depends. Explain how does the resistance depend on the factors stated by you.

A current of 1.5 A flows through a conductor for 2.0 s. What amount of charge passes through the conductor?

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.
