A 0.2-µF capacitor has a periodic waveform v(t)
shown to the right. Determine and plot i(t) over
the range of two cycles.

The resulting waveform should be below the v(t)
and share the same x-axis as demonstrated in
class. Feel free to verify your result in
Multisim. Be neat!

Use Multisim to verify your results. Use the voltage and current probes. Only have
them display the Peak-Peak and the rms values in a 12 pitch font. Remember that
any voltmeter or ammeter in Multisim reads out in RMS. Provide a screen-capture
of the resulting circuit and readings.
