Question

A $2\mu F$ capacitor is charged to $100V$, and then its plates are connected by a conducting wire. The heat produced is :

• A. $0.001J$
• B. $0.01J$
• C. $0.1J$
• D. $1J$

Answer 1

Answer: (B)

$0.01J$

Total amount of energy stored in capacitor $=\frac{1}{2}C{V}^2=\frac{1}{2}\times 2\times {10}^{-6}\times {100}^2=0.01J$
After connecting both the plates total energy will convert into heat
so amount of heat produced $=0.01J$
