Derive an expression for current I passi...

Derive an expression for current I passing through an AC circuit containing only inductor L. Draw a Phasor diagram and graph of v and I versus `omega t`. Explain instantaneous power and the average power.

A

`A*B`

B

`barA+B`

C

`A+B`

D

`barA*barB`

Text Solution

Verified by Experts

The correct Answer is:
D
`barA*barB`
First part of circuit is OR gate and second part is NOT gate. Hence, Boolean equation,
`y=bar(A+B)`
`=barA*barB`
