1.	If the resistances 1Ω, 2Ω, 3Ω, 4Ω are parallel, then the equivalent resistance is?(a) 0.46Ω(b) 0.48Ω(c) 0.5Ω(d) 0.52ΩThe question was asked in a job interview.I need to ask this question from Circuit Elements and Kirchhoff’s Laws in chapter Circuit Elements and Kirchhoff’s Laws of Network Theory
Answer» The correct choice is (B) 0.48Ω For EXPLANATION: The equivalent resistance 1/Rt = (1/R1)+(1/R2)+(1/R3)+(1/R4). And R1, R2, R3, R4 are1Ω, 2Ω, 3Ω, 4Ωrespectively. => Rt = 0.48Ω.
