The diagram illustrates the basic design of an NPN ... current flowing through your body into sound! Part 1: Light Touch Construct the first circuit using a single transistor, an LED, a power ...

Thus the three basic bipolar transistor circuit configurations have equivalents with a FET; common-emitter ... compared to the source, the diode becomes reverse-biased, and no current to speak ...

If you ever work with a circuit that controls a decent amount of current ... N-FETs are like NPN transistors – the gate pin needs to have higher voltage than the source pin for the FET to ...
