What is the need of a resistor or resistence in a circuit?

Open in App

Solution

Dear student,
Resistance in a circuit is used to prevent overheating and Maintain current in circuit. Combination of resistance in an electric circuit can be used to provide a right amount of resistance in the circuit if a single resistor of that amount is not available. So, we can use a varying combination (series / parallel) to get the required amount.
