In the circuit shown below in figure, calculate the value of x if the equivalent resistance between the points A and B is 4 Ω.

In the circuit, there are three parts. In the first part, resistors of 4 Ω and 8 Ω are connected in series. If the equivalent resistance of this part is R' s then R' s = 4 + 8 = 12 Ω In the second part, resistors of x Ω and 5 Ω are connected in series. If the equivalent resistance of this part is R'' s then R'' s = (x + 5) Ω In the third part, the two parts of resistance R' s = 12 Ω and R'' s = (x + 5) Ω are connected in parallel. If the equivalent resistance between points A and B is R p then But it is given that equivalent resistance between points A and B is 4 Ω R p = 4 Ω Putting value of R p in the equation above and solving for x: Hence, the value of x = 1 Ω
