What is an AC voltage rating for a capacitor?

Capacitors have a maximum voltage they can hold as you say, but also have a maximum current they can handle. This is usually referred to as the ripple current spec. Since it''s the current that matters, it can also be expressed as a maximum AC voltage at particular frequencies.

AC voltage ratings for capacitors

Let''s do this properly and explain all the aspects you need to take into account when designing in capacitors on a mains-connected circuit. First, there is the voltage rating. The voltage rating on a capacitor is of course a maximum DC (i.e. a peak) rating. For 50/60Hz mains we''re talking about a sinusoidal voltage waveform with an RMS value of

Capacitance in AC Circuits

In AC circuits, the sinusoidal current through a capacitor, which leads the voltage by 90 o, varies with frequency as the capacitor is being constantly charged and discharged by the applied voltage.

What is the capacitance of a capacitor in AC circuits?

The capacitance of a capacitor in AC circuits depends on the frequency of supply voltage applied to it. In AC circuits the capacitors allow current when the supply voltage is continuously changing with respect to time.
