Question

15. A piece of wire having a resistance R is cut into five equal parts.(i) How will the resistance of each part of the wire compare with

the original resistance?

(ii) If the five parts of the wire are placed in parallel, how will the

resistance of the combination compare with the resistance of the

original wire? What will be ratio of resistance in series to that ofparallel?​

Answer 1

Explanation:

hope this helps you!?.......:-)

Answer 2

Answer:

solved

Explanation:

5 equal parts

each part will have a resistance R/5

(i) How will the resistance of each part of the wire compare with

the original resistance?   R/5 :  R

(ii) If the five parts of the wire are placed in parallel, how will the

resistance of the combination compare with the resistance of the

original wire? R/25 : R

What will be ratio of resistance in series to that of parallel  R : R/25
