Q.5. (i) Consider a conductor of resistance 'R', length
'L', thickness 'd' and resistivity'p'.
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
(iii) Out of the combinations of resistors mentioned
above in the previous part, for a given voltage
which combination will consume more power and
why?

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.
