A current of `2 A`, passing through a conductor produces `80 J` of heat in `10 s`. The resistance of the conductor in ohm is

A

`0.5 Omega`

B

`2 Omega`

C

`4 Omega`

D

`20 Omega`

Text Solution

Verified by Experts

The correct Answer is:
B
`H = i^(2)Rt rArr R = H/(i^(2)t) = 80/(4 xx 10) = 2 Omega`
