Answer:
Total Resistance (Series) R1 = 2Ω + 2Ω = 4Ω
Total Resistance of Series combo in parallel combination R2 = 2Ω + 2= 4Ω
Total Resistance (Parallel) 1/R3 = 1/R2 + 1/2
=> 1/R3 = 1/4 + 1/2
=> 1/R3 = (1 + 2)/4
=> 1/R3 = 3/4
=> R3 = 4/3 Ω
Equivalent Resistance across AB:
=> 1/Rp = 1/R1 + 1/R3
=> 1/Rp = 1/4 + 3/4
=> 1/Rp = 4/4
=> Rp = 1Ω
Option a) 1Ω
