Here are useful EE Reference Documents by Ohmite. Ohmite had created a useful manual that helps proper resistor and power component selection. There is also a valuable reference on Resistors.
Resistor Terminology and Ohm's Law Guide - Ohm’s Law defines the relationships between (P) power, (V) voltage, (I) cur-rent, and (R) resistance. One ohm is the resistance value through which one volt will maintain a current of one ampere
Manual of Engineering Information - An Excellent look at the Basics of Electrical Resistance.
Key to Five-Band Code -This is one code that is Colorfully Encrypted and can only be deciphered by Electronic Enthusiasts.
