Gate, Drain, Source: The Three Pins of a MOSFET Explained With a Water Analogy
Most beginner wiring mistakes with a MOSFET come from one misunderstanding: the gate voltage is measured between the gate and the source, not between the gate and the circuit’s ground. Once that rule is clear, the three terminal names stop being arbitrary and start predicting what a circuit will do. Last updated: October 11, 2026 … Read more
