E field of a capacitor

WebRemember, that for any parallel plate capacitor V is not affected by distance, because: V = W/q (work done per unit charge in bringing it from on plate to the other) and W = F x d. and F = q x E. so, V = F x d /q = q x E x d/q. V = E x d So, if d (distance) bet plates increases, E (electric field strength) would drecrese and V would remain the ... WebJan 24, 2024 · What is a Capacitor? A capacitor is a passive device with two terminals, capable of storing electrical energy in an electric field, much like a small rechargeable battery. It usually has two metal plates on which electrical charges of opposite nature are induced. This generates an electric field in between the plates and develops a potential …
