Answer:

New resistance = 243 ohm

Explanation:

Given:

Current resistance = 27 ohm

Computation:

The wire is extended to three times its initial size, and its cross-section is therefore shortened to one-third of how it used to be. We found the current resistance to be 3x3= 9 times

So,

New resistance = 27 x 9

New resistance = 243 ohm
