i have a zener diode but i dont know about its colour coding and voltage rating. plaese guide me about this
zener diode rating

Hi,
For an experimental determination, place a resistor in series with the zener. It is most convient to have the resistor attach to the cathode. Using a variable voltage supply, place a voltage across the resistor and diode, positive with reference to the cathode. Monitor with a meter across the diode. Increase the voltage at the supply until the voltage reading between the diode's cathode and ground does not change. That will be the zener voltage. Use a resistor large enough in value so the current is in the single milliamps.
