This document summarizes an experiment to determine if a diode is on or off using voltage testing. The experiment involves constructing two circuits with different resistor configurations and measuring the anode, cathode and diode voltages. By comparing the anode and cathode voltages, it can be determined if the diode is forward or reverse biased, and therefore on or off. The results are recorded in a table and calculations are done to verify the diode status against the measurements.

2. Measure the anode voltage (V1) of the diode of figure 1 by connecting the multi-tester parallel to R2, such that positive probe is connected to point A and negative probe is connected to ground.

3. Measure the cathode voltage (V2) of the diode of figure 1 by connecting the multi-tester parallel to 6.8k resistor, such that the positive probe is connected to point and the negative probe to ground.

4. Measure the diode voltage of figure 1 by connecting the multi-tester parallel to the diode, such that the positive probe of multi-tester is connected to point A and the negative probe to point B.

6. Record the measured cathode voltage for figure 1 in Table 1.

7. Compare the measured anode voltage to the measured cathode voltage of figure 1.

8. Which is greater? Based on the comparison, is the diode ON or OFF? Why?

9. Record the measured diode of figure 1 in Table 1.

10. Based on the measured diode voltage of figure 1, is the diode ON or OFF? Why?

11. Record the measured anode voltage of figure 2 in Table 2.

12. Record the measured cathode voltage of figure 2 in Table 1. Compare the measured anode voltage to the measured cathode voltage of figure 2, which is greater? Based on the comparison, is the diode ON or OFF? Why?

13. Record the measured diode voltage of figure 2 in Table 1. Based on the measured diode voltage of figure 2, is the diode ON or OFF?

14. Calculate the diode voltage of figure 1 based on the measured anode and cathode voltages of figure 1. Is the diode ON or OFF? Why? Is the calculated diode voltage equal to the measured diode voltage for figure 1? If there are differences, what accounts for the difference?

16. with a/an OPEN CIRCUIT.

17. If the anode voltage is less than the CATHODE the diode is OFF.

18. For an ON diode. The diode voltage is equal to ZERO.

19. For an OFF diode the diode voltage is LESS THAN ZERO.

20. If the anode voltage is greater than the cathode voltage, the diode is ON and the diode is FORWARD BIAS.504080139148<br />340630516041<br /> FIGURE 1 FIGURE 2<br />CONCLUSION:<br />Base on the experiment we have done. If the diode is on (V1) anode is greater than the (V2) cathode voltage. And it depends on the resistor connecting to this and the voltage across the diode.<br />
