Question

A capacitor is charged to a potential difference of 12 V. it delivers 40% its stored energy to lamp .what is the final potential difference across the capacitor
​

Answer 1

Explanation:

60% will become 0.6 and we will multiply it by 12 we will get 7.2V. A capacitor is charged to potential difference of 12V. It delivers 40% of its stored energy to lamp. The final potential difference across capacitor is 9.295volts.
