A resistance of 40 Ohms is attached to a circuit having current of 300 Amp, Find its voltage.
Correct answer: A. 12000 volts
- A. 12000 volts
- B. 15000 volts
- C. 20000 volts
- D. 300 volts
Explanation
Correct option is B. According to the given formula: V = I R V = 300 × 40 V = 12000 Volt As this is a numerical thus only one option is correct.

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.
