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 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`
