In an `AC` sub circuit, the resistance `R=0.2Omega`. At a certain instant `(V_(A-V_(B))=0.5` volt, `I=0.5 amp` and `(DeltaI//Deltat)=8A//s`. Find the inductance of the coil:

A

`0.01H`

B

`0.02H`

C

`0.05H`

D

`0.5H`

Text Solution

Verified by Experts

The correct Answer is:
C
`V_(A)-V_(B)=V_(L)+V_(R )=(dl)/(dt)+IR`
or `0.5V=Lxx8+0.5xx0.2`
solving, we g et, `L=0.05H`
