# Does capacitor work on AC?

**capacitor**is connected directly across the

**AC**supply voltage. As the supply voltage increases and decreases, the

**capacitor**charges and discharges with respect to this change. A current will flow through the circuit, first in one direction, then in the other. However, no current actually flows through the

**capacitor**.

Keeping this in view, can we charge capacitor with AC current?

Once the **capacitor** is “fully-**charged**” the **capacitor** blocks the flow of any more electrons onto its plates as they have become saturated. However, if **we** apply an **alternating current** or **AC** supply, the **capacitor will** alternately **charge** and discharge at a rate determined by the frequency of the supply.

Similarly, what is the role of capacitor in AC and DC circuit? In **DC Circuit**, the **capacitor** charges slowly, until the charging **voltage** of a **capacitor** is equal to the supply **voltage**. And, when you connect a **capacitor** across an **AC** source, it charges and discharges continuously, due to continuous change in the **voltage** levels.

People also ask, why the capacitor works on AC only?

the **capacitor** begins to oppose the voltage placed on it and eventually there is no more current in the system because the **capacitor** is charged and at equal voltage to the DC voltage source. Now suppose we did the same thing with an **AC** source. Answer: So **capacitance** will work **only** for **AC** supply.

What happens when capacitor is connected to AC?

The **capacitor is connected** directly across the **AC** supply voltage. As the supply voltage increases and decreases, the **capacitor** charges and discharges with respect to this change. A current will flow through the circuit, first in one direction, then in the other. However, no current actually flows through the **capacitor**.
