Also, theres something else im not really clear, is that, if a mosfet had already been turned on so that it conducts, and current is then applied at the source after. will the mosfet heat up? From what I've read, its the point when the mosfet conducts (rise/fall) when current is present at the source that heats up the mosfet. But say it the current wasnt there when it conducts, will that heat up the mosfet? The other thing is, will it even work if there is no current present at the source terminal?
