An Ac circuit with f=1000 Hz consists of a cail of 200 mH and negligible resistance. Calculate the voltage across the coil, if the effective current of 5 mA is flowing.

A

`7.64` V (rms)

B

`7.452` V (rms)

C

`6.28` V (rms)

D

`74.62` V (rms)

(c) Inductive reactance , `X_(L)=Lomega=2pifL`
also , `(E)/(I)=Lomega=X_(L)` or `E=IX_(L) implies E=(5)/(1000)xx1256`
`E=6.28` volt (rms)
