Question

Which of the following does not represent electrical power in a circuit?

• A. \( I^2 R \)
• B. \( V I \)
• C. \( I R^2 \)
• D. \( \frac{V^2}{R} \)

Hint:

Electrical power formulas include \( P = VI \), \( P = I^2 R \), and \( P = \frac{V^2}{R} \).

Answer 1

The Correct Option is C

Electrical power is given by: \[ P = VI = I^2 R = \frac{V^2}{R} \] The expression \( I R^2 \) is incorrect, as power is not expressed in this form.
