B) ground
C) channel
D) base

Question

Quizplus · Accepted Answer

The JFET operates by controlling the width of the depletion region between the p-type and n-type semiconductor of the channel. When a voltage is applied to the gate, it creates an electric field that attracts or repels the majority carriers (electrons or holes) in the channel, thereby changing the width of the depletion region and hence the resistance of the channel. Therefore, the current flowing from the JFET's source to drain must pass through the channel between the depletion layers. The gate is not a part of the current path and is used only to control the current flow by varying the channel resistance. Ground and base are not relevant to the JFET operation.
