Answer :


(a)
Curve A shows the power consumption over a full cycle. As power is given by: Power = Voltage × Current
Increase in amplitude Power Consumption is given as

Here, V is the rms voltage, V0 is the maximum amplitude of the voltage, ω is the angular frequency and t is the time period.
Thus the power curve will have maximum amplitude represented by curve A
(b)
As Power consumption over a cycle includes Positive cycle as well as negative cycle. The average power consumption would be zero.
(c)
From the graph, the current leads the voltage by 90°. In capacitors the current leads the voltage by 90° .
Hence, X is a Capacitor.
