To measure capacitance, you''ll need a digital multimeter, which you can pick up at your local hardware store. First, turn off the power to the capacitor, and connect a resistor across the terminals to drain the charge.
Exploring how capacitors store electrical energy involves understanding capacitance and charge. We start with the basic idea of capacitance, which is measured in Farads, and move to more detailed topics

When sizing a capacitor, always choose one with a voltage rating higher than the maximum voltage in your circuit to prevent breakdown and damage. Capacitance Value: The capacitance value, measured in farads (F), indicates the amount of charge a capacitor can store for a given voltage. Choosing the appropriate capacitance value depends on the
In storing charge, capacitors also store potential energy, which is equal to the work (W) required to charge them. For a capacitor with plates holding charges of +q and -q, this can be calculated: (mathrm { W } _ { mathrm { stored } } = frac { mathrm { CV } ^ { 2 } } { 2 }). The above can be equated with the work required to charge the

It''s important to remember if you use a conventional power source like a battery to charge the capacitor, twice the amount of power (double the Jules stored on the capacitor) will need to be output by the battery. Half of this power will be lost and the other half will remain on the capacitor. This is often explained by claiming the other half of the power is dissipated in the
