Why Does a Capacitor Pass AC? When we connect a capacitor across an AC supply source, it starts charge and discharge continuously due to continuous change in the supply voltage. This is due to changes in AC voltage i.e. AC is positive in the initial cycle for "t = 1" and negative in the second cycle "t = 2" as shown in fig below. In fig 2(a), same happens like in DC connected …
