\tab The purpose of this experiment is to acquire technical skills as well as well as to create a circuit that is able to measure temperature with an analog temperature transducer. After the experiment, the student will be able to answer the following questions. How do you translate a schematic to a resistive circuit on a breadboard? How do you use a multimeter and a DC power supply? How can you use an analog temperature transducer to build a temperature sensing circuit? Do Kirchoff's Current and Voltage Laws (as well as Ohm's Law) accurately represent circuits?
\\ \\ \tab In order to understand the experiment, there are a few concepts the reader must know. Ohm's law is an expression that relates current, voltage, and resistance. It

A multimeter is an instrument that measures voltage, current, and resistance. When acting as a voltmeter, the multimeter displays very high resistance. Contrarily, when acting as an ammeter, the multimeter displays very low resistance. In this experiment, the Agilent 34401 digital multimeter was used. A protoboard is a solderless breadboard that is used to build a circuit. It is important to note that every contact along a row is considered a node, and thus the same voltage runs through those five contacts. A potentiometer is a three terminal device that produces variable resistance. A rotary potentiometer is used in this lab in order to dim an LED light. A transducer is a device that converts one form of energy to another. In this experiment, a temperature transducer (Analog Devices AD592) is used to convert thermal energy to electrical energy. Lastly, a DC (direct current) power supply is utilized in this lab for the generation of both constant voltage (CV and constant current (CC). The specific power supply that is utilized is the Agilent
