The AC's are given by `l_(1)=l_(0)sinomegat,l_(2)=l_(0)cos(omegat+phi)` the ratio of rms values is

A

`1:1`

B

`1:phi`

C

`1:2`

D

`phi:1`

Text Solution

Verified by Experts

The correct Answer is:
A
`l_(rms(1))=(l_(0(1)))/(sqrt(2))=(l_(0))/(sqrt(2))`
`l_(rms(2))=(l_(0(2)))/(sqrt(2))=(l_(0))/(sqrt(2))`
`therefore` ratio `=1:1`
