Capacitance

• It’s the ratio of Net charge on a plate to the potential difference between the plates.

• It’s the ratio net Zero on a plate to the enetial plate

• It’s the ratio of Net change

Capacitors

• It’s devices that is used to store energy

• Area of plates

• Distance between plates

Factors that affect the capacity of a capacitor are :

• Medium between the plates

• Distance between the plates

• Area of the plates

• Time of the plate

The unit of capacitance is :

• Farad

• Ampere

• Volt

• Ohm

Capacitance increases when

• Area increase & Distance between plates decreases

• Area decreases

• The distance increases and area Increase

Capacitance decreases if :

• Area increases

• Area decreases & Distance between plates increases

• Area decreases & Distance between plates decreases

True or false :

Changing the voltage or charge does not affect the capacitance.

• True

• False

True or false:

• Capacitance can only be changed by changing the area, distance between the plates and the insulating material.

• False

• True

• true or false :

• capacitance stays the same if the voltage and charge on the plates increases.

• True

• False

Capacitance only changes if

• Area changes

• Distance between plates change

• Time changes
