A 100 μF capacito

Given

for charged capacitor C₁ =100μF

V=24V

Formula used :

Charge is given by the formula

Q=CV

Where

Q is the charge of the capacitor

C is the capacitance of the capacitor

V is the voltage across the capacitor

Putting the values in the above formula, we get

This capacitor is connected to an uncharged capacitor of C₂=20μF

When a charged capacitor is connected to an uncharged capacitor, then the total charge will be equal to

The potential difference across both capacitors will be the same.

Substitute in eq1)

New potential difference is =

If 100 μF capacitor which is charged to 24V is connected to an uncharged capacitor of 20 μF then potential difference across it is 20V.
