You are given three circuits X, Y and Z when the element X is connected across an a.c. source of a given voltage, the current and voltage are in same phase. When element Y is connected in series with X across the source, voltage is ahead of voltage by pi//4 . But the current is ahead of voltage by pi//4 , when Z is connected series with X, across the source. Identify the circuit elements X, Y and Z. When all the three elements are connected in series across the same source, determine the impedance of the circuit . Draw a plot of current versus the frequency of applied source and mention the significance of this plot.
