Question

Energy stored in a 2000mF capacitor charged to a potential difference of 10V is?
Options
A 100J
Correct Answer
B 200J
C 300J
D 400J
Correct Answer

Option A is the correct answer.

Detailed Explanation

The energy (E) stored in a capacitor is given by the formula E = 1/2 * C * V2, where C is the capacitance and V is the potential difference.Given:Capacitance (C) = 2000 mF = 2000 x 10-3 F = 2 FPotential difference (V) = 10 VE = 1/2 * (2 F) * (10 V)2E = 1 * 100 JE = 100 J.

Hint

Remember the formula for energy stored in a capacitor. Pay attention to unit conversions for capacitance (millifarads to Farads).
