GATE 2016 EC SET B QUESTION 31

In the circuit shown in the figure below:

GATE 2016 Set B Question 31

the magnitude of the current (in amperes) through resistance  R2 is  ____________

Solution

Let current through  R1 = I.
⇒I +0.04Vx =Vx/5
⇒I = Vx/5-Vx/25 = 4Vx/25
Applying KVL,
60= 4Vx/25×5+8×Vx/5
60=12Vx5⇒Vx=25
Thus current through R2 =25/5=5amps

Answer to Question No 31 of Set B of GATE 2016 Electronics and Communication Engineering Paper is 5 Amps
