If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs ...

Thus the three basic bipolar transistor circuit configurations have equivalents with a FET; common-emitter becomes ... We suggested you buy a bag of 2N3904s to experiment with in one of the ...

The transistor is off if the input voltage is less than \(0.7 V\). The mosfet is on, when the input voltage is normally greater than or equal to \(2.0 V\). The mosfet is off if the input voltage ...
