Question

1. A piece of wire of resistance R is cut into five equal parts. These parts are then connected in parallel. If the equivalent resistance of this combination is R', then the ratio is .​

Answer 1

ANSWER IS 25 let R BE RESISTANCE AND Answer: 25

Step-by-step explanation:

Let the length of resistance R be L

Let the resistance of each part after cutting be R  

​

 

Since resistance is proportional to the length of the resistor,

Rs =R 5 i

​

   

=R/25

R/R  

=25
