A wire of resistance R is divided in 10 ...

A wire of resistance R is divided in 10 equal parts. These parts are connected in parallel. The equivalent resistance of such a connection will be

A

`0.01R`

B

`0.1R`

C

10 R

D

100 R

Text Solution

Verified by Experts

The correct Answer is:
A
Resistance of each part = `(R)/(10)`
They are connected in parallel.
Equivalent resistance = `R_(eq)`
`:. (.1)/(R_(eq))=(10)/(R)+(10)/(R)+(110)/(R).....=(10xx10)/(R)=(100)/(R)`
`:. R_(eq)=(R)/(100)=0.01R`
