In an AC circuit, the load has a supply voltage of 240cos(800πt+60) volts and a current of 120cos(800πt+20)mA. What is the simplest two-element parallel circuit can this load have that is equal to the total impedance. Find R,C, L.

What impedance vector (0- j15) Ohms represents:A. A pure resistance.         C. A pure capacitance.B. A pure inductance.       D. An inductance combined with a capacitance.

A capacitor "C", an inductor "L" and a switch "S" are connected in series. When the switch is open, the plate to the left of the capacitor has charge "Qo". The switch is closed the load and current vary sinusoidally with time. Represent graphically the load "Qo" and the intensity of current "I" as a function of time "t", and explain why the current leads the load by a phase difference of 90°.

Solve this ASAP. Figure is also attach.

You have an AC source, which is connected through series connection of an inductor and a resistor to a load. Under what conditions (that is, what type of load), the load voltage may be higher than the source voltage? Explain using phasors
