There are typically between 4 bans and 6 bands on a resistor. You must be very careful when reading them because after a long day working some colors can start to blend. The first 2-3 bands represent single digits, there will then be a band representing the multiplier, a space, and then a tolerance band. On some occasions there will be a temperature coefficient band at the end. The easiest way to learn to read it is to imagine writing the numbers down on paper for example, say we have a resistor with the following colored bands : BROWN, GREEN, RED, GOLD This would represent the following: BROWN - GREEN - RED - GOLD 1 5 X100 +/-5% so it is simply 15 x 100 +/- 5% so you would be holding a 1500 ohm resistor with a 5% tolerance (meaning the resistor value can actually be anywhere between 1425 and 1575)
