Answer 2

Answer:

=> 12.5 ohms

Explanation:

We knew that,

The resistance of a conductor is directly proportional to it's length (L).

L ∝ R

Here we have,

length of wire = 100 cm

it's resistance = 10 ohms

i.e. => 100/10 = 10

L/R = 1

If the wire is further extended by 25 cm,

that is , the new length of wire becomes 1.25 m.

then it's new resistance will be=> 1.25 ×10

=> 12.5
