Metal Oxide Semiconductor Field Effect Transistors (MOSFETs) make for good switches. That is because all it takes is a voltage to determine whether they conduct fully or not. Low signal (typically 0 volts/ground) to the Gate, prevents Drain to Source conduction. This goes for any components that are in series with them as well. They … Continue reading "Brief N Channel Enhancement Mode MOSFET Switch Circuit 2N7000 Transistor"
