Question

Which of the following expressions represent(s) electric power in the circuit?

• A. \( I^2 R \)
• B. \( \frac{V^2}{R} \)
• C. \( VI \)
• D. All of these \bigskip

Hint:

Different power formulas are derived using Ohm's Law (\( V = IR \)) and are interchangeable based on given circuit parameters.

Answer 1

The Correct Option is D

All three formulas correctly represent electrical power: \[ P = I^2 R, \quad P = \frac{V^2}{R}, \quad P = VI \]
