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 R/R' is
a) 1/25
b) 1/5
c) 5
d) 25​

Answer 1

Answer:

HOPE this HELPS.............

Answer 2

Answer:

(d) 25

Explanation:

If the wire of R resistance cut into five equal parts then

each part = R/5 ;(5 parts)

Equivalent resistance ; 1/R' = 5/R x 5

R' = R/25

R/R' = R/(R/25) = 25
