The Digital Multimeter A Digital Multimeter (DMM) is simply an electronic tape measure for making electrical measurements. It may have any number of special features‚ but mainly a Multimeter measures volts‚ ohms‚ and amperes. * Invented in the early 1920s by British Post Office engineer‚ Donald Macadie * It can be used around the house to test flashlight batteries‚ sprinkler valves‚ cables‚ toys and house outlets. * It can Measure to a high degree of accuracy Caution: The Multimeter

methods‚ one with a digital multimeter as well as one with a power supply and an ammeter. The second method has an explanation as to how a thermistor works‚ but I chose the first method because it had a multimeter method‚ which is easier than using a power supply and an ammeter‚ as it reads resistance directly in Ohms. 3. The equipment I will use is an NTC Thermistor‚ Hot Water (200ml)‚ Cold Water (200ml)‚ Beaker (500ml)‚ Thermometer (0-100c)‚ Digital Multimeter‚ and Connecting leads. You will

HOUSE WIRING Wiring is not a duck soup. Period. If you are among those freebies‚ who want to do wiring just because their neighbors are doing it‚ you are on a wrong trail. Wiring is a very serious subject and it’s better to get some information about basicelectrical wiring before you step into it. Any gaffe can burn down your beautiful house in a few minutes. It is a common fact that people get confused when they are cabling for the first time. Gathering some information about circuits‚ wires and

EXPERIMENT NO. 1 INTRODUCTION TO LAB INSTRUMENTS. 1. BREADBOARD We should be familiar to the following things about a breadboard: * What is a breadboard and what is it used for? * How does it work? * Setting Up. * Limitations. What is a breadboard and what is it used for? A breadboard (or protoboard) is usually a construction base for prototyping of electronics. The term "breadboard" is commonly used to refer to a solderless breadboard (plugboard). It was designed by

greater the wattage ratting. Therefore‚ it is important to know the exactly value for each resistor by its code color before using it. Analogue Multimeter‚ every electronic lab has different types of meters. However‚ there are some basic meters that are common and may appear to be different only because they are made by different manufacturers‚ analogue Multimeter must be able to measure dc and ac voltage‚ dc current and resistance.
