Electrostatics Question 128
Question: A capacitor of capacitance $ 6\mu F $ is charged upto 100 volt. The energy stored in the capacitor is [BHU 2003; CPMT 2004; MP PMT 2005]
Options:
A) 0.6 Joule
B) 0.06 Joule
C) 0.03 Joule
D) 0.3 Joule
Show Answer
Answer:
Correct Answer: C
Solution:
$ U=\frac{1}{2}CV^{2}=\frac{1}{2}\times 6\times {{10}^{-6}}{{(100)}^{2}}=0.03J $
