Parallel Circuit:
In a parallel circuit, the components are connected in parallel to each other. This means that there are multiple paths for the current to flow through. Each component in a parallel circuit has its own branch, and the voltage across each component is the same.

Series Circuit:
In a series circuit, the components are connected end-to-end, forming a single path for the current to flow through. The current through each component in a series circuit is the same, and the voltage across the components is divided between them.

Total Resistance:
The total resistance in a circuit is the equivalent resistance of all the components combined. It can be calculated using Ohm's Law, which states that the total resistance is equal to the voltage divided by the current.

Smallest Resistance:
The smallest resistance in a circuit refers to the component with the lowest resistance value. Resistance is measured in ohms, and a lower resistance value means that the component allows a larger current to flow through it for a given voltage.

Explanation:
In a parallel circuit, the total resistance is smaller than the smallest resistance in the circuit. This is because in a parallel circuit, the total resistance is calculated using the formula:

1/RTotal = 1/R1 + 1/R2 + 1/R3 + ...

Since the resistances are added as reciprocals, the total resistance decreases as more resistors are added in parallel. Therefore, the total resistance in a parallel circuit is always smaller than the smallest resistance.

In a series circuit, the total resistance is equal to the sum of the resistances of all the components. Therefore, the total resistance in a series circuit will always be greater than or equal to the smallest resistance.

Hence, the correct answer to the given question is option B) Parallel circuit. In a parallel circuit, the total resistance is smaller than the smallest resistance in the circuit.
