Question

Which of the following derived units is NOT a unit of power?
Options
A Joule/second
B Ampere × volt
C Ampere/volt
Correct Answer
D Volts²/ohms
Correct Answer

Option C is the correct answer.

Detailed Explanation

Power is the rate of energy transfer. Joule/second = watt. Ampere × volt = watt (since P = IV). Volts²/ohms = watt (since P = V²/R). Ampere/volt is siemens, the unit of electrical conductance, not power.

Hint

Recall the formulas for electrical power.
