JEE Mains · Physics · STD 12 - 2. Electric potential and capacitance
In an electrical circuit, a battery is connected to pass \(20\, C\) of charge through it in a certain given time. The potential difference between two plates of the battery is maintained at \(15\, V\). The work done by the battery is ........... \(J\).
- A \(400\)
- B \(300\)
- C \(200\)
- D \(250\)
Answer & Solution
Correct Answer
(B) \(300\)
Step-by-step Solution
Detailed explanation
