Question

A capacitor attached to a 50V battery acquires a charge of 10C over a period of 5 seconds. How much energy is required to charge the capacitor?

Answer 1

answer:

1250 J

Explanation:

The power consumed by a capacitor is given by

\dpi{100} \small P=\frac{1}{2}qV

After finding power, we can calculate the energy used as we are told that the capacitor took 5 seconds to charge. The units of power are watts which can be further broken down into joules per second. By multiplying the time taken to charge the capacitor by the power, we can find the total energy required to charge the capacitor.
