Worksheet: Defining Capacitance

Practice calculating how the capacitance of a capacitor varies with the net electric charge stored on its surfaces and the electric potential difference between the surfaces.

Q1:

What capacitance is needed to store 3.00 µC of charge at a voltage of 120 V?

Q2:

A set of parallel plates has a capacitance of 5.0 µF. How much charge must be added to the plates to increase the potential difference between them by 100 V?

Q3:

Calculate the voltage applied to a 2.00-F capacitor when it holds 3.10 µC of charge.

Q4:

What charge is stored in a 180.0-F capacitor when 120.0 V is applied to it?
