    This document summarizes two experiments in basic electronics: 1) Studying series and parallel resistive circuits to verify Ohm's law and voltage/current divider rules. Different resistor values were used to measure voltages and currents. 2) Measuring Lissajous patterns between two signals to calculate the capacitor value required for a 600 phase shift when connected in series with a 10k resistor. The circuit was set up and the CRO was used to observe inputs/outputs in XY mode to calculate the phase angle.
