How to Calculate Capacitance
Capacitance is the ability of a circuit to store energy. Most often capacitors are used to store this energy in the form of electrical charge. The capacitance of an electrical circuit is measured in farads, and can be found using the charge in coulombs and the voltage.
Charge to Capacitance Formula
The following formula can be used to convert electric charge and voltage to capacitance.
C(F) = Q(C) / V(V)
The capacitance C in farads is equal to the charge Q in coulombs divided by the voltage V.
You can use our series and parallel capacitor calculator to find the capacitance of a circuit when multiple components are used.
For example, let’s find the capacitance of a circuit with a charge of 10 C at 12 V.
C(F) = 10 C / 12 V
C(F) = 0.8333 F
