Question

12. In the circuit shown below in Fig. 8.45, calculate the
value of t if the equivalent resistance between the
points A and B is 422
802
W​

Answer 1

I hope the question is not in agreement with the figure. But fortunately I can explain you the way the question in the figure can be done.

both 4 ohm and 8 ohm are in series. let us call it X

both x ohm and 5 ohm are in series. let us call it Y

We can see X and Y are in parallel connection. 1/X + 1/Y is the equivalent resistance, which will already be given in the question. Read and calculate accordingly.
