A 100 watt bulb is operated by 240 volts, the current through the bulb will be:
Correct answer: C. 0.416 A
- A. 2.4 A
- B. 240 A
- C. 0.416 A
- D. 41.6 A
- E. 416 A
Explanation
Power = voltages * current100 = 240*ICurrent = I = 10/24= 5/12= 0.4166A

About Current Electricity
Steady current relates charge flow to potential difference, resistance and resistivity, including how temperature changes a conductor's resistance. Sources with internal resistance have terminal voltage below their emf when delivering current, and maximum power output occurs under a specific load condition rather than at zero resistance.
