If the cross-sectional area of the channel in n-channel JFET increases

1.	If the cross-sectional area of the channel in n-channel JFET increases, the drain current__________(a) is increased(b) is decreased(c) remains the same(d) decreases exponentially then increaseThis question was addressed to me in final exam.My doubt stems from Transconductance Amplifiers topic in division Differential and Multistage Amplifiers of Electronic Devices & Circuits
Answer» The correct choice is (a) is INCREASED For explanation: The gate source junctions are reverse biased as a RESULT depletion regions from which extend to the bar by changing gate to source voltage; effective cross sectional area decreases with the function of the gate to source voltage. With INCREASING the cross section area of the channel, the drain current is increased.
