We, have: For resistance, Rn and Rm in parallel, = + Req RnRmRn Rm For resistance, Rn and Rm in series, = + Req Rn Rm Now, above circuit can be reduced to an equivalent circuit with , VT Req : R2 and R3 are in parallel, = + = . R23 R2R3R2 R3 2 5 Ω , R4 R5 and R6 are in parallel, = + + = Req1 R4R5R6R4R5 R5R6 R4R6 103 Ω , R1 R23 and Req1 are in series, = + + = Req R1 R23 Req1 1556Ω Hence, (a) = = = .
