JEE · NEET Previous Year Question
An uncharged capacitor is connected to a battery. While charging the capacitor, how much is the energy lost, from the energy supplied by the battery?
Topic: JEE PYQ
Answer: A. Full step-by-step solution below.
- A
- B
- C
- D
Correct answer: A
Solution
(a) Let the capacitance of the capacitor is and the emf of the battery is V.Then, charge given to the capacitor is .
Work done by the battery is, V. i.e., the battery supplies this energy.
Energy stored in capacitor, .
Remaining energy i.e.,
amount of energy is lost.
