Electrostatics Question 640
Question: If there are $ n $ capacitors in parallel connected to a$ V $ volt source, then the energy stored is equal to
Options:
A) $ CV $
B) $ \frac{1}{2}nCV^{2} $
C) $ CV^{2} $
D) $ \frac{1}{2n}CV^{2} $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] The energy stored by any system of capacitor is $ E=\sum{\frac{1}{2}CV^{2}=\frac{1}{2}nCV^{2}} $
