Question

Capacitance 15F and 5F are connected in parallel across a 20V battery. What is the energy stored?
Options
A 4000J
Correct Answer
B 0.004J
C 200J
D 400J
Correct Answer

Option A is the correct answer.

Detailed Explanation

C_eq = 15 + 5 = 20F. E = ½ CV² = ½ × 20 × 400 = 4000J.

Hint

For parallel capacitors, C_eq = C1 + C2. Then use E = ½ CV².
