Question

The resistance of a conductor is 27 ohm. If it is cut into three equal parts and connected in parallel, then its total resistance is

Answer 1

Given, resistance =27ohm

if it is divided into three parts then resistance of one resistor will be 9ohm

formula to be applied 1/R=1/R1+1/R2+1/R3=1/9+1/9+1/9=3/9

=9/3=3ohm

hence R=3ohm

hope it helps.

Thanks.
