You are given 10 resistors each of resistance `2 Omega`. First they are connected to obtain possible minimum resistance. Then they are connected to obtain possible maximum resistance. The ratio of maximum and minimum resistance is .... .

A

100

B

10

C

2.5

D

25

Text Solution

Verified by Experts

The correct Answer is:
A
Maximum resistance when connected in series.
`R_(S)= 20Omega`
Minimum resistance when connected in parallel.
`R_(p)= (2)/(10)Omega`
`(R_(S))/(R_(P))= (20)/(2//10)= 100`
