A capacitor is charged through a potential difference of 200 V, when 0.1 C charge is stored in it. When it is discharged, the energy it will release would be:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 10 J
The energy stored (U) in a capacitor is -
$U=\frac{1}{2}qv$
$=\frac{1}{2}×0.1×200=10J$
