Capacitor Set 4 2022

The simplest form of capacitor is made out of

• three metal plates and between the plates is an insulating material

• two metal plates and between the plates is a dielectric material

• one metal plate and a dielectric material

What is a dielectric material?

• It is a poor conductor of electricity

• It is a conductor

• it is an insulator

• It is a good conductor of electricity

Capacitors are used to store....

• charges

• energy

• electricity

• two plates

The charging of the capacitor will stop when....

• when the capacitor is overheated

• the charging will never stop. it is a continuous process.

• when the potential difference across capacitor matches the power supply connected to it

What happens to the charge on the plate during discharging?

• the charges flow from one plate to the other through a resistor until the charge on the plate is zero.

• the charges move from one plate to the other across the dielectric gap between the plates

• the charges do not move and stay on the plates.

What happens to the current in the circuit during discharging of the capacitor?

• current remains constant

• current increases to a maximum value

• current decreases until it becomes zero
