Then we tested the voltage of the meter probes set on 2K ohms with another meter set on 20V. The meter read 0.6V which is enough voltage to push through the binary layer of the diode. Then we tested the diode for voltage in both direction. From anode to cathode it read 0.52V and from cathode to anode it read 0V. This means it is working good.
We built a circuit with both a diode and a resistor in it and tested the voltage drop across the resistor and the voltage drop across the diode. The resistor had 13.37v drop and the resistor had 0v drop.
Next we tested the amp flow through the diode which was 0.01A and voltage supply was 13.39V.
The voltage drop across the resistor and diode was added together and compared to the supply voltage which was 13.37v.
Now we tried the same experiment with a higher resistance resistor. The voltage drop across the resistor was 12.67v and voltage drop across the diode was 0.6v. Amp flow through the diode was 0.006 amps.
This showed that the more resistance there is, the less amp will go through.
Lastly we created a circuit with a LED instead of a diode. We measured the voltage drop across the resistor which read 11.46V, the current flow through the LED which was 0.001amps and the supply voltage which was 13.39V. This test proved that the LED has less voltage drop because the LED has a light in the component which is a load
It was quiet hard to put together with LED and resistor because we did different from other groups later on we connect the same way as others like connect directly from the battery. if somebody make the circuit then we just look through that, i would feel bored but by thinking and making the circuit, i felt time went so fast that i thank that i didn't miss the class
