Question

Which of the following is a practical reason for using a series combination of resistors in an electrical circuit?

This question was previously asked in
RRB Group D 2025 Question Paper (18-Aug-2026) (Shift 1)
The correct answer is

To increase total resistance and limit current

In a series circuit, the same current flows through every resistor, and the total resistance equals the sum of the individual resistances.

This higher total resistance is used deliberately to limit the current drawn from the source, protecting the circuit.

Hence, this is the correct answer.
