Unformatted text preview: UNIVERSITY OF MISSOURI - COLUMBIA DEPARTMENT OF MECHANICAL AND AEROSPACE ENGINEERING MAE 3800 Instrumentation and Measurements Laboratory Spring 2010 EXPERIMENT #1 Resistance, Voltage, and Current measurement Due: 5:00pm, Tuesday, Feb. 2 1 Introduction: This initial experiment is designed to familiarize yourself to basic electrical measurements of resistances, voltages, and currents. 1.1 Objectives To use a digital multimeter (DMM) for resistance, voltage, and current measurements To measure the output characteristics of solar cells 1.2 Equipment: Fluke digital multimeters (DMM) A potentiometer serving as a variable resistor Solar cells An AC circuit with a concatenated resistor 1.3 Report format For this experiment you do not have to write a report. Use the REPORT BOOKLET to record and analyze results, and hand it in in lieu of a report. 2. Description of Equipment Digital multimeters (DMM) are versatile instruments that combine the measurements of several electrical quantities in a single unit. The versatility of the instruments seems to complicate the measurements of basic electrical quantities. Fortunately, the meters are very intuitively designed and their usage is easy to learn. It is very important to realize that the circuit connection for current measurement is different from that for resistance measurement or voltage measurement. This has been explained in the lecture. Solar cells convert solar rays into electric energy. They behave like batteries. When several cells are concatenated in series, the output voltages increase in proportion to the number of the cells....
