Question

a length of a wire 2m and its area of cross section is 2ms if the resistivity of the wire is 4×10^-8 ohms meter find the resistance of the wire what will happen to the new resistance of the wire if the new length is made double to the original length​

Answer 1

Answer:

Resistance be increased.

Step-by-step explanation:

Ro is l/a

Because. Length is directly proportional to resistance

If lenght increase than resistance will increase
