A series RLC circuit is driven by an AC voltage source with peak voltage of 5 Volts.  The peak current in the circuit is 0.1 Amps.  The peak voltage across the resistor is measured to be 4 Volts.  The peak voltage across the inductor is measured to be 10 Volts, and the peak voltage across the capacitor is measured to be 7 Volts.  The three peak voltages across the components in the circuit add up to more than the peak 5 Volts of the source.  Explain how this can be.  What is the impedance of the circuit?  Is this circuit inductive or capacitive?  Will the voltage in the circuit lead or lag the current?  Explain how you arrived at your answers.
