diodes

diodes practical, we first meassure the resistance in the diodes on 2k with a ohmmeter,anode to cathode is 0 ohms and same results 0 for cathode to anode.The we set on 2k ohms with another meter set on 20v to test the voltage on the meter probes, we have 0.64v so its a pass for voltage going though the binary layer of the diode,then we tested voltage on teh dioldes from both ways, anode to cathode is 0.52v and cathode to anode its infinity which means we have a working diodes. we then built a circuit with a diode and a resistor in it and test for voltage drop across the resistor and diode, 13.2v on the resistor and diode had none. then its the ampflow though the diode which is 0.01amp and voltage was 13.4v.

we then tried the same test but with a higher resistance resistor,the voltage drop on the diodes was 0.5v and voltage drop across resistor is 12.6,amp flow is 0.005amps and the result is the higher resistance there are the low amp we will get.

and at last we made a circuit with a LED we measure the voltage drop and reads 11.4v,the current going though the lED is 0.001amps and power supply is 13.39v and as result that the we get lesser voltage drop in the LED because the component in the light is a load.
