Let us discuss the question on network theory of GATE EC 2023

Q. In the circuit shown below.

The current i flowing through 200 Ω resistor is ___ mA.

Ans. In this question we have to calculate the current.

Now, we will redraw the circuit and simplify the circuit by using V=IR

Step -1 :- Applying source transformation , we get circuits as

Step-2 :- Applying KCL at node VA

\frac{V_{A}-2}{2000}+\frac{V_{A}}{2000}-1+\frac{V_{A}+1}{1000+200}=0 V_{A}\left [ \frac{1}{2} + \frac{1}{2} +\frac{1}{1.2} \right ]=1+\frac{1}{2}-\left ( \frac{1}{1.2} \right )

VA= 0.636 V

Step-3 :- Calculating the current

i=\frac{V_{A}+1}{1000+200} i=\frac{0.636+1}{1.2}

i= 1.36 m A

So, simply by simplifying the circuit and applying source transformation , we can solve the problem. Then by observing the circuit just think logically that whether KCL is applicable or KVL. In this way, we can solve any network related problem.

Hope, so. You have well understood the solution of the problem.
