Answer 2

Answer:

A combination of resistance in an electric circuit can e 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.

equivalent resistance-

the equivalent resistance is that value of resistance, which when replaced in place of the combination, will continue to give the same performance for the part of circuit outside this combination.
