This the first lesson: black, brown, red, orange, yellow, green, blue, purple, gray and white. These colors
correspond to the numbers 0, 1,2, 3, 4, 5, 6, 7, 8, 9. Then the last part of this concept is when resistor
are made they have a tolerance. Which means the difference + or - that a resistor can be and still a
usable component. The tolerance that is allowed with resistors is 10% +or- for silver and 5% +or- for
gold. So just like reading a book. We also read a resistor for left to right. The last band painted on the
resistor is the tolerance given by the manufacturer. So there you have the first part of this basic
principle about resistors.

This next lesson is about ohms law. This is a formula that is used to measure electronic circuits. For all you car audio
people this is vital to you. The reason this and other formula's are vital. Because audio is all about frequencies. The
human ear has a range of around 400Hz to 15000 KHz. Now lets not get going to fast. The other reason for this wonderful
ohms law is to measure power. So if we could not calculate power! Guess what? Those expensive components we are
connecting and building in our cars. Might blow up! Do you have thousands of dollars to replace all your amps, woofer,
sub-woofers, tri-axial and dual cone speakers. Because all the output coming through the wire has to be impedance
matched. Impedance matched means that the load resistance attached to the stereo output should be equal. Lets say if
the load output on the Kenwood amp and the kicker speakers is 150 Ohms. So know we have made a complete circle of
Kirchhoff's Law. In layman's terms ohms law.

Hey, its me again Dave. Lets get back to learning Kirchhoff's Law or Georg Simon Ohms' Law. Kirchhoff by the
way was a German physicists. Greg Ohm was a Bavarian physicists. The reason that I intermix the two is because
they both have to do with voltage, resistance and current. I am sure there are advance people that are saying now
your talking. But everyone needs to learn the basics. Remember, I said that I would start from the beginning to
the end. Hey if I croak or something. Well maybe I have a safety net on some other storage media. Ohms law
states I = E/R, E =R*I and R = E/I. Now I will tell you what each of these values represent. I stands for Current, E
stands for the Voltage and R stands for the Resistance. Kirchhoff states that electrical energy is the movement of
electrons past a certain given point in time.

How many of you have a DOM or a Digital Volt Ohm Meter. The price on this piece of equipment has dropped drastically.
This type of meter will give you a relatively accurate reading on any project. I recommend that you get a meter and a
grounding strap. These are the basic pieces of equipment that will be required for out study. We will continue with the
theory of electronics. What this means is how electrical elements flow. Lets take a copper wire for instance current flows
on the outer shell of the wire. It will take the path of least resistance. You will also find that as a circuit generates more
power it creates heat.

Well we all need to start off somewhere! I know so many people will be way ahead of this
level of electronics. But I will start at the beginning so we are all in the same place. The
main reason is because electronics has really grown. Well I will not start at the time
before there were automobiles. That would do you no good at all. So I will start with just
a few simple formula's or rhythmic sayings that help us remember very important
properties. The first lessons is to remember the resistor color code.
