Question

I) consider a conductor of resistance r', length l', thicknessd' and resistivity '. Now this conductor is cut into four equal parts. What will be the new resistivity of each of these parts? Why? (ii) find the resistance if all of these parts are connected in: (a) parallel (b) series

Answer 1

Explanation:

Resistivity will remain the same

In series resistance is r

And in parallel resistance is r/16
