Sample questions

1. 1.A car bulb connected to a 12 volt battery draws 2 A current when glowing. What is the resistance of the filament of the bulb? Will the resistance be more, same or less when the bulb is not glowing?
2. 2.Define electrical energy and explain how it is related to the work done in an electrical circuit.
   • A.Electrical energy is the energy consumed by an electrical device when current flows, equal to the work done in moving charge Q through potential difference V (W = QV).
   • B.Electrical energy is the power dissipated in a circuit, calculated as the product of current and resistance (P = I²R).
   • C.Electrical energy is the force exerted by electrons in a circuit, measured in joules per second (J/s).
   • D.Electrical energy is the voltage drop across a resistor, given by Ohm’s law (V = IR).
3. 3.An electric kettle rated 250 V can bring a certain amount of water to its boiling point in 8 min. If it is connected to 200 V mains, calculate the time in which water comes to its boiling point.
   • A.2.15 min
   • B.12.5 min
   • C.5.45 min
   • D.3.45 min
4. 4.Calculate the current drawn by an appliance rated 110W, 220V when connected across 220V supply.
5. 5.Four resistances of 2.0 Ω each are joined end to end to form a square ABCD. What is the equivalent resistance of the combination between any two adjacent corners?
   • A.1.0 Ω
   • B.1.5 Ω
   • C.2.0 Ω
