Question

Why do we combine resistors?
With explanation pls

Answer 1

it is very difficult to attain a certain value of resistance in a circuit if we want value of R to be large or bery small.

we cannot use a single resistance of very large value as it woul lose energy in the form of heat.

so to attain a certain value we combine resistance of small values in series or parallel

Answer 2

Answer:

we combine resistors bcouz to find equivalent resistence in a place of various used resistance in electric circuit
