Draw a labelled diagram to show the domestic electric wiring from an electric pole to a room. Give the wiring for a bulb and a three-pin socket only.

What is the difference between direct current generator and alternating current generator?

Draw a labelled diagram of an electric motor. Explain its principle and working. What is the function of a split ring in an electric motor?

A coil is connected to a galvanometer. When the N-pole of a magnet is pushed into the coil, the galvanometer deflected to the right. What deflection, if any, is observed when:

(a) the N-pole is removed?

(b) the s-pole is inserted?

(c) the magnet is at rest in the coil?

State three ways of increasing the deflection on the galvanometer.
