Question

Which of the following derived units is NOT a unit of electrical 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

Electrical power P = VI = I²R = V²/R. So units: Joule/s (Watt), ampere×volt, volts²/ohm are all power. Ampere/volt is 1/ohm, which is conductance (siemens), not power.

Hint

Power = voltage × current.
