Question

consider a conductor of resistance R,length L, thichness d, and resistovity p, now this conductor is cut into four equal parts. what Will be new resistovity of each of these parts?why

​

Answer 1

Answer:

We know that resistivity is a material properties and does not depends on the physical dimensions.So even wire cuts in 4 equal but still resistivity will remain same. So the answer is, resistivity will be same. For given voltage parallel connection consume more power because it have low equivalent resistance.
