Sample questions

1. 1.Two lamps one rated 100 W, 220 V and the other rated 60 W, 220 V are connected in parallel to a 220 V supply. What current is drawn from the supply line?
2. 2.Why is it necessary to have an earth wire installed in a power circuit, but not in a lighting circuit?
   • A.Power circuits handle higher currents and appliances with metallic bodies, requiring earthing to prevent electric shocks.
   • B.Lighting circuits use thicker wires that do not require earthing for safety.
   • C.Power circuits operate at lower voltages, making earthing unnecessary.
   • D.Lighting circuits are always installed outdoors, eliminating the need for earthing.
3. 3.Which of the following methods can be used to increase the speed of rotation of an electric motor?
   • A.By increasing the strength of current in the coil.
   • B.By decreasing the strength of the magnetic field.
   • C.By reducing the number of turns in the coil.
   • D.By increasing the resistance of the coil.
4. 4.Which of the following best describes a solenoid and its magnetic behavior when current is passed through it? (Refer to the figure below)
   • A.A cylindrical coil of wire that produces a uniform magnetic field inside, with one end acting as North pole and the other as South pole.
   • B.A straight wire that generates a circular magnetic field around it when current flows.
   • C.A permanent magnet shaped like a cylinder with fixed North and South poles.
   • D.A coil of wire that only produces a magnetic field when placed near another magnet.
5. 5.The potential difference between terminals of a cell in a closed electric circuit is:
   • A.terminal voltage
   • B.electro motive force
   • C.voltage drop
   • D.none of these
