    Name: _____________________ Wire Resistance and Ohm’s Law PhET MiniLab Introduction: When an electrical potential exists in a circuit‚ a current may flow. Current is the flow of electrons in a circuit. Resistance in the circuit slows the flow of the electrons‚ reducing the current in the circuit. We will use the mathematical form of Ohm’s Law frequently when we investigate electric current and circuits later in this unit. • Open the PhET Simulation Electricity‚ Magnets‚ and Circuits ( Resistance

    2006 "Ohm’s Law is the relationship among electric current‚ resistance‚ and voltage. The principle is named after the German scientist George Simon Ohm." –Webster’s Online Dictionary. I will be discussing the uses of Ohm’s Law and why it is so important in everyday electrical problems whether it be simple or not. It is everywhere and used by many whether they notice it or not. Ohms law states that current in amperes is equal to voltage divided by resistance. This form of ohms law is most useful

    Study about Ohm’s Law: • To verify Ohm’s Law by calculating voltage‚ current and resistance based on different views of Ohm’s law as well as measuring those values to compare the theoretical results with the actual results. • To verify the relationships of R-I‚ V-I and R-V given ohm’s law by increasing one parameter while holding the other parameter constant‚ then measuring and calculating equivalent results of the third parameter. What is Ohm’s Law: Ohm’s Law is made from 3 mathematical equations

    wire will increase. Background: Some materials have consistent resistance at the same temperature regardless of how much voltage is applied through them‚ these materials are known as ‘Ohmic’ resistors. This is because they are said to obey Ohm’s law‚ which states that if a voltmetre is used to measure the voltage (V) of an unknown resistance (R)‚ and an ammetre is used to measure the current (i) through the same unknown resistance‚ then ‘R’ would be given by R = V/i . The eureka wire used in this

Purpose The purpose of this lab is to help understand how voltage‚ current and resistance are closely related to one another. The outcome from this lab is to be able to differentiate when to use ohmmeter and voltmeter for the individual circuit. II. Theory Ohm’s Law states that the electric current through a material is directly proportional to the voltage across a piece of material (such as wire) while the resistance is held
