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 RR is:

(a) 125
(b) 15
(c) 5
(d) 25

Open in App
Solution

(d) 25

The wire is cut into 5 equal parts, each resistance will be of R5. All the 5 parts are connected in parallel.
Therefore, equivalent resistance (R') is given as
1R=5R+5R+5R+5R+5R = 5+5+5+5+5R = 25R
RR = 25
