The capacitance of this capacitor is 8.85 x 10² F.
Given -
The Plate Separation is 4cm.
The Capacitor Plate has area 0.04m²
The permittivity has value of 8.85 x 10².
When two parallel plate connected with potential the plates are charged and Electric field is generated. Capacitors have a strong hold on storage devices . Energy storage is one of the merit of capacitor.
Discharging and charging of the capacitor is the simultaneous cycle of the mechanism.
