In following LCR circuit find Z, i(t), `V_(OC) , V_(OL) at resonace frequency

Text Solution

Verified by Experts

`Z=Z_(min)=R=2Omega`
`i_(0)=E_(0)/Z=10/2=5A`
`i(t)=(V(t))/Z=5sinomegat`
`V_(OL)=i_(0)X_(C)=100` volt
`V_(OL)=i_(0)X_(L)=100` volt
Note : Above circuit is used as voltage amplifier (magnification) as peak value of voltage by source is only 10 while we can have maximum voltage up to 100 `(V_(OC) " & "V_(OL))`
