What is the current flowing through the R1 resistor for voltage divider (R1=R2=1KΩ, VDD=10V)?

(a) 5mA

(b) 3mA

(c) 1mA

(d) 2mA

The question was posed to me by my school principal while I was bunking the class.

This interesting question is from Biasing the FET topic in portion Field-Effect Transistors of Electronic Devices & Circuits

Best answer
Right answer is (a) 5mA

The best I can explain: IR1=IR2 =VDD/R1+R2

=>IR1 = 10/2KΩ

=>IR1 = 5mA.
