From wikipedia: Four-band identification is the most commonly used color coding scheme on all resistors. It consists of four colored bands that are painted around the body of the resistor. The scheme is simple: The first two numbers are the first two significant digits of the resistance value, the third is a multiplier, and the fourth is the tolerance of the value. Each color corresponds to a certain number, shown in the chart below. The tolerance for a 4-band resistor will be 2%, 5%, or 10%.The Standard EIA Color Code Table per EIA-RS-279 is as follows:
From Wikipedia: A resistor is a two-terminal electrical or electronic component that resists an electric current by producing a voltage drop between its terminals in accordance with Ohm's law: R = \frac {V}{I} The electrical resistance is equal to the voltage drop across the resistor divided by the current through the resistor. Resistors are used as part of electrical networks and electronic circuits.
Does anyone know what kind of wires (copper,silver,etc.) that these use?
megaman - the wires used in these electronics is usually pure gold, but that is not the best part... it is what's inside that is really cool... resistors, for example, use rare natural diamonds! You should rip those things out of the walkie talkie and bring them to a reputable jeweler... I bet they are worth a fortune!

I'm not exactly sure where you got the natural diamonds idea, unless you consider carbon graphite powder diamonds... Resistors are mostly made from carbon powder mixed in a ceramic composition, then coated with a plastic resin, no diamonds here. And as for them being worth a fortune.. WTF! That doesn't even make sense, if companies make and sell resistors for pennies a piece, why wouldn't the companies sell them to jewelers themselves??? Think about what you say before you say it.
I don't know if Megaman can afford all that... I suggest he start with a free tutorial like http://electronics-for-beginners.com/index.php(and yes, I was being sarcastic)... his reply of "really?" made it all worth while!Sorry for having fun at your expense Megaman, no hard feelings... Feel free to email/pm me anytime if you have a question about components. The good part is that you are learning! I see that you figured out that the strped hot dogs were resistors. You even found a chart that explains how to understand the colors. So let's see if you can put it all together... If you have a lightbulb hooked up to a battery through a resistor, would the lightbulb be brighter if the resistor had orange-yellow-brown-gold stripes or if the resistor had blue-brown-red-silver stripes? This is not a trick question or anything... just want to make sure that you are actually learning what each component does.
