Experiment 3: Multimeters Physics 114 Kasey Lanier Lab Partners: Meret Cruz, Shannon Moore 2.9.11 Objective: We sought to employ the proper use of a multimeter and learn to read voltage, current and resistance. The purpose of this experiment was to learn how to use a multimeter to read current, voltage, and resistance. It was also crucial to learn the proper use of the meter in circuit in to obtain the correct data as different setups will obtain different data.

Introduction: The topic of current is crucial to understand electricity and to the subject of Physics and its application to observing and measuring the world. In this experiment, we employed electrical meter to measure properties of electrical circuits including but not limited to resistance of resistors, inductance of inductors and capacitance of capacitors. An electrical meter can also measure active properties such as voltage and current. We used a multimeter (which can be a ammeter, voltmeter, ohm meter and diode checker). For our experiments, the DC ammeter and voltmeter functions were utilized. An ammeter measures the flow of charge or current through a wire or electrical device and has low resistance so it must be in series with the circuit. These series circuits can be traced in one single path from one component to another. Conversely, a voltmeter measures “voltage drop” or difference in electric potential between two points in a
