Electrostatics Question 80

Question: A $ 2\mu F $ capacitor is charged to 100$ volt $ and then its plates are connected by a conducting wire. The heat produced is [MP PET 1999; Pb. PET 2003]

Options:

A) $ 1\ J $

B) $ 0.1\ J $

C) $ 0.01\ J $

D) $ 0.001\ J $

Show Answer

Answer:

Correct Answer: C

Solution:

Heat produced = Energy of charged capacitor $ =\frac{1}{2}CV^{2} $

$ =\frac{1}{2}\times (2\times {{10}^{-6}})\times {{(100)}^{2}}=0.01J $
