Current flowing through 
equals to one tenth 
of 
(Drain current). For the
value of Drain current
, the value of resistors 
and 
are respectively?
A. 
B. 
C. 
D. 
Please scroll down to see the correct answer and solution guide.
Right Answer is: D
SOLUTION
For dc analysis, we redraw the circuit as
This is n-channel MOSFET. The drain current for the MOSFET is defined as
or 
or 
Since, source is connected to ground, i.e.
So, the voltage across 
is
Since, the gate current in MOSFET is 
, so current 
flows through
resistances 
and 
. Therefore, we have
Applying KVL in loop 1, we get
or 
Thus,
