Question

Energy to charge a 10 µF capacitor to 100 V? (Capacitance value missing unit)
Options
A 0.05J
Correct Answer
B 0.01J
C 0.5J
D 0.01J
Correct Answer

Option A is the correct answer.

Detailed Explanation

Assuming C=10 µF = 10×10⁻⁶ F, V=100 V. U = ½ × 10⁻⁵ × 10⁴ = ½ × 0.1 = 0.05 J.

Hint

U = ½ CV².
