Capacitor Charge / Energy Calculator
The calculator can find the charge (expressed in
coulombs) and energy (expressed in joules) stored in a capacitor. Enter the voltage across
the capacitor and the capacitance of it. The charge and energy
will be shown on the right. The formulae used in the calculations can be found
here in the technical data section.
Calculate Charge (Q) & Energy (J) from Voltage (V) & Capacitance (C):
Charge: Q = CV
where C is the capacitance in Farads, V is the
voltage across the capacitor in Volts and Q is the charge measured in coulombs (C).
Energy stored: W = ½ QV = ½ CV2
where W is the energy measured in Joules.
