Answer:
Circuit (b)
Step-by-step explanation:
In parallel combination of resistors, the current flowing in each branch divides while the potential difference remains the same in entire circuit. The equivalent resistance is given by the following formula as :
While in series combination, the current remains the same while the volatge across each resistor is different. Their equivalent is given by:
In the given figure, circuit (b) shows parallel combination of resistors. Also, the resistors are connected in two different paths in circuit (b).
