The current in an LCR circuit is given by `I=20sin (100pi t+(pi)/(6))A`. The voltage across the the inductance L of `0.1 H` at t = 0 will be

A

`31 .4 V `

B

`3.14 V `

C

157 V

D

314 V

Text Solution

Verified by Experts

The correct Answer is:
D
`V = (20 xx 100 pi xx 0.1) sin `
` ( 100 pi t + ( 5pi )/(6))`
`V = 200 pi sin "" ( 5pi)/(6)`
` V = 314 V`
