Question

Suppose we want to reduce the resistance for a fixed length of wire (conductor) by half the original resistance value , what can be done without changing the material for wire.​

Answer 1

Answer:

don't know dear

ask on doubtnut

Answer 2

Answer:

answer is here

Step-by-step explanation:

we know that the resistance is inversely proportional to the area of cross section

thus if we double the area of cross section then the resistance become half of the original value without changing the material of wire.

I hope it will help you to know the concept of resistance which is depend on which factors
