Answer Notes
A Junction Field-Effect Transistor (JFET) consists of three specific terminals: the gate, the drain, and the source. Current flows through the semiconductor channel between the drain and the source. The voltage applied to the gate terminal creates an electric field that pinches off or opens this channel, regulating the current flow.
It is important to keep device terminals distinct. For example, "emitter, base, collector" are the terminals of a Bipolar Junction Transistor (BJT), not a JFET.
