For capacitors connected in parallel, the voltage equals the lowest voltage rating of either capacitor. For example, wiring two 22-mfd/150-volt capacitors in parallel results in a 44-mfd/150-volt capacitor. Both voltage ratings are equal, so the resulting voltage is 150 volts.
the capacitor is tested, sleeved and labeled, packed and finally shipped. DEVICE PHYSICS A capacitor is physically created when two conductors are sep-arated by an insulator known as a dielectric.
