Working of Capacitor
Capacitor is an electronic component that stores electrical energy.
Inside the capacitor, the terminals connect to two conducting metal plates separated by an insulator.
This is the symbol of capacitor.
Connect a battery across the capacitor.
Charging of capacitor:
The plate that is connected to the negative terminal of the battery accepts electrons from battery.
In this way the capacitor is fully charged.
Once the capacitor is fully charged it has same voltage as the battery.
Discharging of capacitor:
The plate that is connected to the positive terminal of the battery losses electrons to the battery, so that the capacitor discharged.
