title: RC, RL circuit
aka:  square wave into RLC circuit, ringing

Description:
A Pasco signal generator produces a square wave (about 5 hz) into an RLC circuit on a board.  
Using DataStudio, the input waveform is compared to the waveform found over the capacitor and resistor.  A large coil is used for the inductor.

Questions:
    How does the wave form observed change with the following modifications?
    A. The capacitor is increased.
    B. The inductance is changed (increased or decreased?) by inserting a piece of iron into the coil.
    C. The time period of the square wave is decreased.
