Question

A wire of resistance R is cut into five equal pieces. These five wires are then connected in parallel. If the resultant resistance of this combination be R then the ratio of resultant to the original will be ?

Answer 1

A wire of resistance R is cut into five equal pieces = the resistance of each piece = R/5
 
If five pieces of R/5 each are connected in parallel
The resultant resistance of the parallel combination 

Answer 2

5R:R BECAUSE THE FIVE PEICES ARE IN PARALLEL ANT THAT IS EQUAL TO R/5


AND
R/R/5=5R/R
