Resistor Color Codes

First lets look at the different colors found on resistor and what values they represent.

resistor color codes

Resistors have either 4 or 5 bands of color on them. The first two (or three in the case of a 5 band one) give the value of the resistor. The next one gives the size of it (or the multipiler) and the last gives the tollorance. Lets have a look a a sample resistor.

We can see that this one has four bands, brown - blue - brown and gold. The first two is the value brown = 1 blue = 6, ie 16. The next one gives the multiplier, brown = 1 ie 10 ohm. 16 times 10 ohm = 160 ohm with gold =5% tolorance. So this is a 160 ohm resistor with %5 tolorance.

Shouldn't the voltage division equation be: Vout = Vin(R2/(R1+R2))???

What do the different colours of resistor the mean? (ie. blue resistor vs brown vs green)

Generally vin is greater than vout,
but by thge above voltage division rule, it is quite the opposite how come?

resistor is used in ciruit to limit the current

Resistors Have no polarity; they can be installed either way, but often it is best to put them in all facing the same way so as to make reading them easier.

Do they need to be put in a circuit in a certain way (positive, negative)? if so, how do I tell what end from the other?

The answer to this is mainly to do with the tolorance on the resistors. If you have 10-20-30-40....1000, there is not much difference between 990 and 1000 and 990 is well within the tolorance of 1000. So they start with a even number and jump up by the tollorance. For example with 10% tollorance it starts at 10 and the goes 12 (2 = 10% of 10 times by 2), 15, 18, 22, 27, 33, 39, 47, 56, 68, 82 so all the ranges are covered evenly. So 10 cover 9,10,11 and 12 covers 11,12,13 and 15 covers 14,15,16 and so on.

Hey, Why do resistors have odd values like 47k and 56k, but not 50k? Wouldn't it be alot easier to keep them at rounded values?
