What is the difference between a'resistance' and a 'capacitor'?
assistant
A capacitor is an electrical component that stores energy in an electric field. It is made up of two conducting plates separated by an insulator, such as air or a vacuum. An electrical charge builds up on one plate and then quickly discharges to the other plate. The amount of time it takes for the charge to transfer from one plate to the other is called the “RC time constant”. Resistors are used to control current flow and can be either fixed or adjustable.
