Understanding Resistors , Poteiometers & Rheostats

 This Mini Course explains the different Components associate with Resistance in an Electronic Circuits . The Instructor Clearly Explains the Resistor Color Code and tolerance of Fixed resistors and gives explanation on of the difference between a 4 Band Resistor and 5 Band Resistor. After the instructor Explains and demonstrates the correct steps in calculating the resistor value from the color band  of the Resistor. Then the instructor goes into the tolerance band and the the different tolerance values (i,e.10%  5% 1% ) and how to calculate the Resistance window for each of the tolerance bands. After the  instruction, there are Plenty of Examples and Exercises for the student to master the the instruction given by the Instructor. In the 2nd part of this mini course the Instructor Clearly Explains Poteiometers and Rheostats and the difference between them. The instructor explains the the correct way and technique on how to to measure the resistance of each, Then at the end  of this section in this course the instructor gives examples of applications that use a potentiometer and rheostats. At the end of the  Course the Instructor gives an explanation and examples of Varisters and Thermometers and there Electronic symbol and examples of there  application(s).
