Capacitors in Parallel Calculator

The calculator on this page can be used to determine the total equivalent capacitance of up to four (4) capacitors in parallel.

Capacitors are said to be in series when there is a single current path that travels through each capacitor in order.

Capacitors are in parallel when there are multiple current paths that may have different values of capacitance.

One of the most important quantities that tells us about the total capacitance in the circuit is the equivalent capacitance .

Capacitors in series vs. parallel.

Even though capacitors may come in complex configurations, we can often model the circuit as a single capacitor. This capacitor would have the value of the equivalent capacitance of the whole circuit.

Formula for Capacitors in Parallel

Capacitors in parallel add their values of capacitance simply, making it easy to calculate their equivalent value. You can think of any capacitors in parallel as essentially functioning as a single capacitor.

To find the total capacitance in a parallel circuit (or a single branch of a parallel circuit), you just add up the capacitances of everything in the circuit (or branch).

C_{eq} = C_1 +C_2+C_3+...+C_N
