Question

a jfet always operates with
select one:
○ a. the gate connected to the source
○ b. the gate-to-source pn junction forward-biased
○ c. the drain connected to ground
○ d. the gate-to-source pn junction reverse-biased

Explanation:

A JFET (Junction Field - Effect Transistor) operates by controlling the channel conductivity. The gate - to - source pn junction in a JFET is always reverse - biased. If it were forward - biased (option b), it would conduct like a diode and not function as a JFET. Connecting the gate to the source (option a) or the drain to ground (option c) is not a fundamental operating condition of a JFET. The reverse - biased gate - to - source junction creates a depletion region that can be used to control the channel width and thus the current flow in the JFET.

Answer:

d. the gate - to - source pn junction reverse - biased
