Question

The energy required to charge a 10 μF capacitor to 100 V is ____________

(a) 0.01 J

(b) 0.05 J

(c) 5 X 10^-9 J

(d) 10 X 10^-9 J

This question was posed to me in my homework.

I'd like to ask this question from Advanced Problems on Network Theorems topic in portion Useful Theorems in Circuit Analysis of Network Theory

Answer 1

Correct answer is (b) 0.05 J

For explanation I would say: E = \(\frac{1}{2}  CV^2\)

= 5 X 10^-6 X 100^2

= 0.05 J.
