Purpose

The purpose of this lab is to give students experience in building circuits that exhibit ohmic and non-ohmic behaviors, allow students some practice experimenting with voltage dividers, and give students some experience in working with virtual instruments.

Procedure

In this experiment several circuits were made for testing resistance, it's laws, and many of it's other useful properties. The first was a circuit with two power sources used to test Kirchhoff's laws usefulness in obtaining the actual occurrences of a circuit. The second circuit was made to test the properties of a resistor by fitting a curve to the current passing through the resistor based on the voltage across it. This same circuit was used to test if a light-bulb exhibits the same Ohmic properties. The final two circuits were made to test how the the voltage changed across the load of a voltage divider depending on where the resistance was varied from.
