Detailed explanation-1: -Answer: The correct answer is option a) series. The total resistance in a series circuit is the sum of all the resistance in the circuit, hence it is more than the biggest resistance.
Detailed explanation-2: -A circuit with parallel connections has a smaller total resistance than the resistors connected in series.
Detailed explanation-3: -The total resistance in a parallel circuit is less than the smallest of the individual resistances. Each resistor in parallel has the same voltage of the source applied to it (voltage is constant in a parallel circuit).
Detailed explanation-4: -In series combination of resistors, the total resistance is more than the highest resistance.
Detailed explanation-5: -Answers. in a parallel circuit, the equivalent resistance=1/sum of the reciprocals of all the re-sistances in the circuit. Hence it is smaller than the smallest resistance in the circuit.
