What charge, in units of millicoulombs, is stored when a voltage of 9.6 v is applied across a 34 mf capacitor?

326.4 mC

Explanation:

The relationship between charge, capacitance and voltage in a capacitor is given by

where

C is the capacitance

Q is the charge

V is the voltage

In this problem, we have

C = 34 mF is the capacitance

V = 9.6 V is the voltage

Re-arranging the equation and substituting the numbers, we find the charge stored in the capacitor:

it is called kinetic energy
