Construction/Operation
• There are three electrodes: source, gate, and drain electrodes.

• The resistance between terminals B and A (between drain and source) changes according to the voltage (gate voltage) applied to terminal E (gate).
• When the gate voltage increases, the resistance between terminals B and A decreases, allowing the current to flow easily.
