Capacitors

Basics of a Capacitor

• In its most straightforward form, a capacitor is a electric device built of two parallel plates separated by an insulating material called the dielectric
• From the impartial condition, both plates possess an equivalent amount of free electrons
• If a voltage source is connected to the capacitor, electrons have been removed from 1 plate along with also an equivalent quantity have been deposited about Another plate
• No electrons flow through the dielectric (insulator)
