Hardware Tools A. Electrostatic Discharge(ESD) 1. Antistatic Wrist Strap-An antistatic wrist strap‚ ESD wrist strap‚ or ground bracelet is an antistatic device used to safely ground a person working on very sensitive electronic equipment‚ to prevent the buildup ofstatic electricity on their body‚ which can result in electrostatic discharge (ESD). It is used in the electronics industry by workers working on electronic devices which can be damaged by ESD‚ and also sometimes by people working around

represents the placement of the linear displacement sensor. V2represents the output measured by the connected multimeter. Initially‚ slider of the linear displacement sensor was all the way to the side and the multimeter displayed a reading zero. As the student pushed the slider along its track from 0 cm to 6 cm at 1 cm increments‚ using a metric ruler‚ the reading given through the multimeter was recorded. Once 6 cm was reached‚ the slide was placed back to where it first began. This process was repeated

In this project you will need to measure the amount of electrolytes in the drinks I will do this by using a multimeter. A multimeter is an electronic device that measures voltage‚ current‚ and resistance. This is the main and the most important object in our project. A good concentration of electrolytes in your blood is very healthy. The cells allow your nerves to send

Physics assignment Aim To determine which factors affect the resistance of a conductor‚ and the mathematical relationship that exists between these variables. Hypothesis Copper wires would be a better conductor than nichrome wires because it would yield less resistance when they have same cross-sectional area‚ length and temperature. Resistance would be increased when length wires increased. Resistance would be increased when cross-sectional area of wires decreased. Resistivity of wires is a factor

Voltmeter A voltmeter is an instrument used for measuring electrical potential difference between two points in an electric circuit. Analog voltmeters move a pointer across a scale in proportion to the voltage of the circuit; digital voltmeters give a numerical display of voltage by use of an analog to digital converter. The first digital voltmeter was invented and produced by Andrew Kay of Non-Linear Systems (and later founder of Kaypro) in 1954. RHEOSTAT A rheostat is a device which is used

circuit‚ draw one out. No circuit is “too simple” to need a schematic. If the circuit is simple‚ the schematic should be easy to draw. Verify each connection on the circuit using the multimeter. Some multimeters have a continuity checker which will ring when a low-resistance connection is made. Even if your multimeter doesn’t have this feature‚ set it for the lowest resistance setting. If you read 0 (or very low number of ohms) between the test leads‚ they are wired together. Use a highlighter

Faculty of Engineering & Computing Laboratory Report Title of Experiment: Series and Parallel Circuits Date Given: January 28‚ 2013 AIM: To investigate the circuits to tell whether the resistors are in parallel or in series also to determine the internal resistance of a 1.5V cell. THEORY: In this experiment it was expected of the experimenter to have a basic knowledge of circuits in both aspects theoretically and practically. A basic circuit comprises of a cell or power supply

voltage drop across the diode was almost the same each time. This lab showed the effects of current and voltage in a parallel circuit. This experiment also showed how the brightness was effected by changing the voltage. Equipment and materials: • Multimeter • Power Supply • Connecting wires • A bread board • A 330 ohm resistor • A l k ohm resistor • 2 Red LED’s Theory: A light-emitting diode (LED)‚ is an electronic light source. The first LED was built in the 1925 by Oleg Vladimirovich Losev
