A capacitor is a device that stores electrical charge. The simplest capacitor is the parallel plates capacitor, which holds two opposite charges that create a uniform electric field between the plates.. Therefore, the energy in a capacitor comes from the potential difference between the charges on its plates.

500 watt-hours is 62.5 amp-hours, assuming the voltage is 8 volts (V). Determining the amp hours from watt hours is reasonably straightforward, especially if you know the voltage. You may use the formula: Charge = Energy / Voltage. So, you figure out the amp hours, which is the unit of charge, by dividing the watt hours, the energy, by the voltage.

Joules is a direct relationship, one Joule here equals one watt-second not watt-hour so to get your energy in joules you have to multiply your watt-hour in the figure by 3,600 because it''s 3,600 seconds in an hour. So if you do that and you look at a double a triple a and a double a better you triple a battery 1.4 watt-hours.

Set the multimeter to measure capacitance. Most digital multimeters use a symbol similar to –|(– to signify capacitance. Move the dial to that symbol. If several symbols share that spot on the dial, you may need to press a button to cycle between them until the capacitance symbol appears on the screen. If your tool has several capacitor settings, choose …
