Resistor, Types of resistor, Example, colour code. PowerPoint: Using Photos and Video Effectively for Great Presentations. Online Course. A PowerPoint presentation by L. A resistor has two terminals across which electricity must pass, and is designed to drop the voltage of the. Chapter 5: Resistors. What is a resistor? Definition: A device used in electrical circuits to maintain a constant relation between current flow and voltage. Resistors.
Resistors. Topics Covered in Chapter 2. Types of Resistors. Resistor Color Coding. Variable Resistors. Rheostats and Potentiometers. Variable resistors are called potentiometers There is a fixed value of resistance between two terminals The moving part of the potentiometer is called the wiper. Resistors can be either fixed or variable in value; Fixed resistors come in a variety of different shapes, sizes and forms; Axial lead resistors have the value of .
What is a resistor? Why use resistors? Resistor codes Resistor tolerances How is it measured? Resistance in Series – A free PowerPoint PPT presentation. These circuit symbols are for drawing schematics in PowerPoint. For an example Series safety: ohm series input resistor to limit power-on surge current. .yes, the humble resistor! and that goes for the coolest mobile phone around or any other device. Of course mobiles, laptops etc. don't just use resistors. Equivalent Resistance. Basic Laws of Circuits. Equivalent Resistance: We know the following for series resistors: Figure Resistors in series. Req = R1 + R2.
