How does a capacitor work?

An electric field forms across the capacitor. Over time, the positive plate (plate I) accumulates a positive charge from the battery, and the negative plate (plate II) accumulates a negative charge. Eventually, the capacitor holds the maximum charge it can, based on its capacitance and the applied voltage.

What is the capacitance of a capacitor?

The ability of the capacitor to store charges is known as capacitance. Consider the following circuit, which shows the working principle of a parallel plate capacitor with a dielectric between them. Apply the voltage V as shown in the circuit, with plate 1 being positive and plate 2 being negative. An electric field appears across the capacitor.

How does a capacitor charge a battery?

When the voltage is supplied to these plates, plate 1 will carry a positive charge from the battery, and plate 2 will carry a negative charge from the battery. The voltage is supplied for a period of time, during which time the capacitor is charged to its maximum holding charge, and this period is referred to as the capacitor's charging time.

What happens when voltage is applied to a capacitor?

When voltage is applied to the capacitor in such a way that, the positive terminal of the battery is connected to the left side plate of the capacitor and the negative terminal of the battery is connected to the right side plate of the capacitor, the charging of capacitor takes place.

Why do capacitors have two conductive plates?

The two conductive plates of the capacitor are good conductors of electricity. Therefore, they can easily pass the electric current through them. The conductive plates of the capacitor also hold the electric charge. In capacitors, these plates are mainly used to hold or store the electric charge.
