OBJECTIVE The objectives of this experiment are to investigate and verify the Thevenin’s theorem and to investigate and verify the Norton’s theorem. EQUIPMENT Resistor 100Ω‚ 1kΩ and 4.7kΩ‚ digital multimeter(DVM)‚ bread board. INTRODUCTION Some circuits require more than one voltage source. Superposition theorem is a way to determine currents and voltages in a linear circuit that has multiple sources by taking one source at a time. the current in any given branch of a multiple-source linear

Conductors and Insulators of Electricity A major reason electricity works is because of conductors. First metal‚ water‚ tall trees and tall items are good conductors because lightning is attracted to them. These materials have many mobile electrons. Metal is an easy substance for lightning to travel through so metals are good conductors. However‚ rubber is a bad conductor because lightning bounces off of it. A bad conductor is called an insulator. An insulator has a few mobile electrons. It is

circuit and study the results‚ to see they are reliable. This investigation will mainly show the accuracy and how reliable my main investigation is‚ changing anything that is unreliable and needs corrected. I have learned that it is important to use a multimeter because it shows an accurate digital reading of the resistance and I don’t have to work out the resistance manually which can give me a fairer test due to possible mistakes with calculations. It will also cut down the amount of components in the

taking voltage‚ current‚ and resistor measurements. One of which‚ is to use a standard multimeter to take measurements. However‚ all measurements in this lab report come from the digital NI ElVIS board. A. Resistance: Given three resistors of different color codes‚ the theoretical resistance can be found by apply the standard color code. Following this value‚ one can find the actual resistance by using the multimeter feature of NI ELVIS by attaching the positive and negative leads of the board to the

Title: Resistors in Series and Parallel Date: 17/7/05 Aim: The aim of this experiment is to compare the predicted and actual resistance in a circuit of resistor combinations in series and in parallel. Background: A resistor is an electrical component/device that has electrical resistance. Resistors can be used in electric circuits for protection of components‚ voltage division or current control. In an ideal resistor the resistance remains constant regardless of the applied voltage or current
