i was wondering, and i know many people here should know this...
what is the purpose of a relay?
why doesent current go straight from the switch, to the load...
an example would be a car horn
you push the horn, the relay clicks, then the horn goes BEEEEEP
what is the downside of making it go straight from the switch to the actual horn?
