If the equation of alternating emf is V ...

If the equation of alternating emf is V = 200 sin 300t, then for a circuit containing R = 100 `Omega` and L = 800 mH, the peak value of current will be in ampere :

A

0.77

B

`2.0`

C

1.5

D

1.83

Text Solution

Verified by Experts

The correct Answer is:
A
`X_L=(300xx800)/1000`=240
R=100
`i=V/Z =200/sqrt(100^2 + 240^2)`
