In the circuit given below the value of resistance, Req is ___________(a) 10 Ω(b) 11.86 Ω(c) 11.18 Ω(d) 25 ΩI got this question during an interview for a job.Question is from Advanced Problems on Network Theorems in chapter Useful Theorems in Circuit Analysis of Network Theory

Answer»

The correct option is (c) 11.18 Ω

Explanation: The circuit is as shown in figure below.

Req = 5 + \(\frac{10(R_{eq}+5)}{10 + 5 + R_{eq}}\)

Or, \(R_{eq}^2 + 15R_{eq}\) = 5Req + 75 + 10Req + 50

Or, Req = \(\sqrt{125}\) = 11.18 Ω.
