Question

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

Answer 1

Answer:

4.8V

Explanation:

given potential difference=12V

it gives potential difference to lamp =40%

final potential difference across the capacitor=40/100×12

=4.8V
