text: The light energy emitted by a flash is supplied by the capacitor, and is proportional to the product of the capacitance and the voltage squared; photoflash capacitors have capacitance in the range 80-160 microfarads (μF) and voltages from 180–330 volts for flash units built into small disposable and compact cameras, increasing for units delivering higher light energy.
