Consider a series AC circuit with L = 3.5mH, R = 50Ω, C = 10μF, and E0 = 60V.

1) Find the amplitude of the current, f = 1250Hz.

2) Explain in words why the amplitude of the voltages across the capacitor, resistor, and inductor can add up to more than the amplitude of the voltage of the power supply?

3) Find the phase angle for the circuit at f = 1250Hz, what does this angle indicate is happening in this circuit?

4) Describe in detail what happens to the amplitude of the current as the frequency reduced to 580Hz.

5) Draw a phase diagram for the circuit at f = 580Hz.
