Mood said:electrical current changes the atomic structure of the wires and resistors into a different state, and if you keep on turning it on and off it gets warped in a sense.
leaving it on means it'll maintain its electrical atomic structure instead of constantly changing it.
(does this make sense or just pure bull?)
