Answer to Question #8164 in Electric Circuits for farooq
what is the relation between branch resistance and the total resistance of a parallel circiut?
Let's assume that the circuit consists of N branches with Ri, i=1..N resistance each. Then the total resistance of a circuit is
R = 1/( 1/R1 + 1/R2 + 1/R3 + ... + 1/RN ).
