The new resistance = 27 / 3 = 9 due to the wire being divided into three pieces.
Three resistances are now linked in a parallel fashion.
1 / r = 1 / r1 + 1 / r2 + 1 / r3
1 / r = 1 / 9 + 1 / 9 + 1 / 9
1 / r = 3 / 9
1 / r = 1 / 3
r = 3 ohm
A uniform wire with a resistance of 27 ohm is divided into three equal pieces and then they are joined in parallel. Find the equivalent resistance of the parallel combination.
