Resistor colour codes

Resistor values are encoded as colour codes . Here we are talking about 3 band resistor col0ur coding system and how to remember it easily . The colour coding system is as below

The number starts from 0 and ends at 9 . Lets take the first letter of each colour

B B R O Y G B V G W ( 0 1 2 3 4 5 6 7 8 9 )  . Here is an easy way to remember it

Example:

The 1st and 2nd band is the number and the third one is the multiplier for 10 ( if its 3 => 10 raised to 3  or 10^3 ) . And the third band is for tolerance

Resistors are measured in ohms, and have a wattage rating. Resistance value is marked on the resistor in an internationally accepted color code. Normally quarter-watt resistors are used in the following circuits unless otherwise specified. Carbon film and metal film resistors are generally used. Wire wound resistors are used for higher wattage resistors.
