COMEDK · Physics · 18. Capacitance
A \(10 \mathrm{mF}\) capacitor has been charged to a potential of \(100 \mathrm{~V}\). Suddenly if it explodes, the energy given out is
- A \(50 \mathrm{~J}\)
- B \(10^{5} \mathrm{~J}\)
- C \(50 \mathrm{~mJ}\)
- D \(10^{3} \mathrm{~J}\)
Answer & Solution
Correct Answer
(A) \(50 \mathrm{~J}\)
Step-by-step Solution
Detailed explanation
Given, capacitance, \(C=10 \mathrm{mF}=10^{-2} \mathrm{~F}\) Potential, \(V=100 \mathrm{~V}\) When capacitor explodes, then its whole stored potential energy is given out in the form of heat and lightning.…
