Hi all. With mosfets, such as the one at this link here …click here……
This question relates to using a mosfet as a relay switch … if there’s no voltage across drain and source, then the drain-to-source path (for the N-channel mosfet) can’t be just open-circuited or short-circuited simply by controlling the gate-to-source voltage, right? In other words, the mosfet isn’t the ‘same’ as an open-circuit/short-circuit relay switch, right?
Eg… if the drain is left open-circuited (not connected to anything), then will applying a gate-to-source voltage (and removing that voltage) repeatedly cause the resistance between drain and source to go low and high repeatedly?
