Lcr Circuit Graph. The frequency response curve of a series resonance circuit shows that the magnitude of the current is a function of frequency and plotting this onto a graph shows us that the response starts at near to zero reaches maximum value at the resonance frequency when i max i r and then drops again to nearly zero as ƒ becomes infinite. The resonance in series lcr circuit occurs when inductive reactance is equal to capacitance reactance i e x l x c.
See also section precautions. So correct graph is a. Instead of analysing each passive element separately we can combine all three together into a series rlc circuit.
Alternatively when the frequency of applied a c.
At f res measure v l v c along with v r. So circuit will be inductive. Alternatively when the frequency of applied a c. V l 171 66 v v c 72 6 v v r 13 68 v.
