Question

The channel of a JFET is between the ________

(a) gate and drain

(b) gate and source

(c) drain and source

(d) input and output

The question was asked by my school teacher while I was bunking the class.

My doubt is from Transconductance Amplifiers in section Differential and Multistage Amplifiers of Electronic Devices & Circuits

Answer 1

Right choice is (c) drain and source

Easy explanation: The field effect transistor is a three terminal device that is constructed with no PN-junctions within the main current carrying path between the Drain and the Source terminals. The current path between these two terminals is called the “channel” which may be made of whichever a P-type or an N-type semiconductor material.
