Find the gate voltage for voltage divider having R1=R2=1KΩ and VDD=5V?

(a) 1V

(b) 5V

(c) 3V

(d) 2.5V

I got this question in an internship interview.

My question is based upon Biasing the FET topic in portion Field-Effect Transistors of Electronic Devices & Circuits

Correct answer is (d) 2.5V

Easy explanation: VG = R2×VDD/R1+R2

=>VG=1×5/2

=> VG= 2.5V.
