Capacitor in Electronics
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
Run Capacitor vs. Start Capacitor: What''s the Difference?
Start capacitors usually have a much shorter lifespan than run capacitors. This is because they are designed to take on much higher levels of stress during the startup phase of an induction motor, leading to components wearing out faster. As such, start capacitors should be checked for proper operation on a regular basis and replaced as necessary.
