AC capacitors are designed to handle alternating current, which means the voltage and current change direction periodically. They are typically used in applications such as motors, generators, and power supplies. On the other hand, DC capacitors are specifically designed for direct current, where the voltage and current flow in a single direction.
When a capacitor is connected to a DC source, the current increases initially, but as soon as the applied voltage is reached at the capacitor’s terminals, the current flow stops. In AC circuits, the alternating current alternately charges the capacitor in one direction and the other at regular intervals.
When a capacitor is placed in a DC circuit that is closed (current is flowing) it begins to charge. Charging is when the voltage across the plates builds up quickly to equal the voltage source. Once a capacitor reaches its fully charged state, the current flow stops. Once a charged capacitor is disconnected from a circuit it will remain charged.
This characteristic allows capacitors to "block" DC current flow. In AC circuits the alternating current periodically changes directions, charging the capacitor in one direction and then the other. As the plates discharge during the change of direction, the capacitor output current alternates in phase with the AC voltage.
Capacitors in AC circuits are trickier than DC. This is due to the alternating current. In AC circuits capacitors resist the current. The capacitive reactance is the capacitor resisting the sinusoidal current and is symbolized by XC. Since it is resisting the flow of current the unit for capacitive reactance is ohm.
The capacitor will charge to the level of the applied voltage when DC current is applied to a circuit that just contains resistance and capacitance. Once the capacitor is fully charged, there is no further current flow because DC only flows in one direction. Capacitors are able to “block” DC current flow according to its property.
