A total charge of 90 coulombs flows in a conductor during a time of 5 min. The strength of current in the conductor will be

A

0 . 5 A

B

0 . 4 A

C

0 . 3 A

D

0 . 2 A

Verified by Experts

The correct Answer is:

C

Given ` q = 90 C, t = 5 xx 60 s `
300 s
`I = (q)/( t) = (90)/( 300) = 0 . 3 A `
