Answer 1

Answer:

Explanation:

vd) Resistance of a piece of wire is proportional to its length. A piece of wire has a resistance R. The wire is cut into five equal parts. Therefore, resistance of each part =R/5  

All the five parts are connected in parallel.  

∴equivalent resistance (R') is given as
