  • By using colour code u can find resistance value..it is very easy if u understand it once..u can find example of this on www.allaboutcircuits.com

  • By color code as follow: Digit, Digit, Multiplier = Colour, Colour x 10 colour in Ohm’s (Ω) For example, a resistor has the following coloured markings; Yellow Violet Red = 4 7 2 = 4 7 x 102 = 4700Ω or 4k7 Ohm.

  • 1. If Voltage and current is given then : r=v/i;br /2. If you have the resistor physically, Use Colour code..

  • Hold the resistor with the gold or silver band to the rigjt and read the color codes from the left to the right. select the color codes from the bands on the resistor. Read the colors from left to right. The resistance value based on the color code provided is now displayed.
