The energy stored in a capacitor of capacitance \(10 \mu \mathrm{~F}\) when charged to a potential of 6 kV is
- A 100 J
- B 200 J
- C 180 J
- D 160 J
Answer & Solution
Correct Answer
(C) 180 J
Step-by-step Solution
Detailed explanation
\( E = \frac{1}{2} C V^2 \) \( E = \frac{1}{2} (10 \times 10^{-6} \, \mathrm{F}) (6 \times 10^3 \, \mathrm{V})^2 \) \( E = 180 \, \mathrm{J} \)
