An electric current is passed through a ...

An electric current is passed through a circuit containing two wires of the same material connected in parallel. If the lengths and radii of the wire are in the ratio `(4)/(3)` and `(2)/(3)`, then the ratio of the currents passing through the wires will be

A

`(1)/(3)`

B

`(3)/(1)`

C

`(4)/(3)`

D

`(3)/(4)`

Text Solution

Verified by Experts

The correct Answer is:
A

`V-iR` `V=` constant
`i_(1)R_(1)=i_(2)R_(2)`
`(i_(1))/(i_(2))=(R_(2))/(R_(1))`
`thereforeRprop(l)/(A)`
