Intro to Resistors

4 Basic components

There are basically four components in electronics They are:

1  Resistors

2  Diodes/Transistor

3  Inductors/Coils

4  Capacitors

What is a resistor?

Resistor resist the flow of electricity. 

Here is it's schematic syllable:

Resistor Color Code

To determine the value of a resistor (or how much resistance a resistor has) we use this color code system.




To help you understand the color code system, complete this assignment.

Alternative assignment (recommended) :

Have each student take several random resisters, decode them, and then check there work with a Meeter.
