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

0.01 R

B

0.1 R

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)`
`therefore (1)/(R_(eq))=(10)/(R)+(10)/(R)+(10)/(R)` . . .
`=((10xx10))/(R)=(100)/(R)`
`therefore R_(eq)=(R)/(100)=0.01R`
