6. A series circuit contains the following elements: a 125Ωresistor, a 175 mH inductor, two 30.0? F capacitors
   and a 40.0? F capacitor. Voltage is provided by a 235Vmgenerator operating at 75.0 Hz.
   a. Draw a schematic diagram of the circuit.
   b. Calculate the total capacitance of the circuit.
   c. Calculate the capacitive reactance.
   d. Calculate the impedance.
   e. Calculate the peak current.
   f. Calculate the phase angle.
   g. Resonance occurs at the frequency when peak current is maximized. What is that frequency?
