Question

State whether the following statement is True or False.

The series combination of resistors is used when the resistance in the circuit is to be increased or the current is to be decreased.

Answer 1

This statement is true.

Explanation:

• In a series combination, the equivalent resistance equals the sum of the individual resistances, so the total resistance of the circuit increases.
• For the same applied voltage, an increase in resistance decreases the current (I = V/R).
• Therefore, a series combination is used to increase resistance or decrease current, e.g., a rheostat connected in series controls the current in a circuit.
