Introduction: In this experiment, you will study a small, inexpensive electric motor used as a crude elevator. You will measure the current through, and voltage across, a motor as it lifts a small mass. If you know the current and voltage, you can calculate another electrical quantity power. The power used by an electrical device can be calculated from power. The unit of power is the watt. An electrical device that consumes 1 W converts one joule of energy to another form every second. If the power provided to a device is constant over time, you can multiply the power by the time and get the energy. If the power provided to a device changes during the experiment, the electrical energy can be determined by finding the area under a power vs. time graph. Safety: In this lab we will be dealing with a lot of electrical wires, and a circuit board. We should not act goofy, and rush to conclude the experiment, because it can lead to horrible consequences, and mis-lead data. Other than this, just follow general lab safety rules and follow your professor’s instructions thoroughly. Materials: 1. LabQuest 2. utility clamp 3. Small wooden dowel rod 4. Vernier Current Probe 5. Connecting wires with clips 6. Vernier Differential Voltage Probe
