Answer 1

Answer:

There are n similar conductors each of resistance R . The resultant resistance comes out to be x when connected in parallel. If they are connected in series, the resistance comes out to be.

Answer 2

Answer:

The resistance of n wires each of resistance r have equivalent resistance of R ohm when connected in parallel.

or, 1/r+1/r+1/r........n times=1/R

or,n/r=1/R

or,r=nR.............(1)

The connected in series the equivalent resistance will be

r+r+r+........n times=nr=n(nR)=n²R

Answer n²R
