A wire of resistance R 1 is cut into five equal pieces. These five pieces of wire are then connected in parallel. If the resultant resistance of this combination be R 2 , then the ratio is:

Question

Philoid · Accepted Answer

When the wire is cut into 5 pieces, resistance of each part is R/5

So, equivalent resistance of the 5 pieces when connected in parallel is

R₁ = R/25

So required ratio R: R₁=25:1

A wire of resistance R1 is cut into five equal pieces. These five pieces of wire are then connected in parallel. If the resultant resistance of this combination be R2, then the ratio is:
