The circuit that contains resistors linked either in series or parallel to each other could be replaced by a circuit that has similar resistance. The resistance that is equivalent to the resistance of two resistors that are connected in parallel equals the reverse of the reciprocal sum for each individual resistance. This is the resistance in the circuit that contains the resistors in series is the total of all the resistances.

a) 2+ 3 + 6 = 11 ohms

b) 3 + 3+ 3 = 9 ohms

Ans: Part a, 11 ohms

Part b, 9 ohms
