An infinite ladder is constructed with 1 Ω and 2 Ω resistor shown below. The current I flowing through the circuit is ___________(a) 8.18 A(b) 0 A(c) 9 A(d) 10 AI got this question in an interview for internship.Asked question is from Advanced Problems Involving Complex Circuit Diagram topic in section Network Theory and Complex Circuit Diagram of Network Theory |
Answer» RIGHT ANSWER is (c) 9 A The best explanation: Equivalent RESISTANCE, REQ = R = 1 + (2 || R) Or, REQ = 2 So, I = \(\frac{18}{2}\) A = 9 A. |
