Transistor as a switch - low side or high side

Transistor as a switch - low side or high side Get 5 boards in about a week for $22! In this video we look at transistor as a switch. That means the transistor goes from fully off (cutoff) to fully on (saturation). As we look at this use of the transistor we look at where in the circuit relative to the load should we place the transistor. Before or after the load. Finally we look at using a BJT NPN to switch. an N channel MOSFET. Yes!! I now have merch: Electronics themed T-Shirts! HEY YOU ABOUT TO POST SOMETHING STUPID: Yes, I know my hands are large/fat. It’s because of a heart condition I suffer from called Congestive Heart Failure. Here’s a link to some information about CHF: One of the symptoms is that is causes fluid retention, mostly in the hands, feet/ankles, and face. It will kill me one day.
