1. Using your VOM, select a low resistance meter range and connect the positive lead of the VOM to the diode's anode teminal, while the negative lead, cathode's teminal, as shown in Figure 1.1. measure the resistance reading. 2. Now reverse the VOM's leadto that the meter's positive leadis connected to the cathode and the negative lead the anode. Note the resistance reading. This is the reverse resistance. 3. Connect the circuit as shown in Figure 1.2. Adjust the DC power supply to give a voltage across the 1Kohm as shownin Table 1.1. For each voltage, measure and record the DC voltage drop (Vp) across the diode. Detemine the diode current by using the Ohm's law in each voltage value. 4. Plot the resulting curve (diode curent versus diode voltage). Graphically, detemine the diode bamier potential (V3), and forward resistance (R2), record your results in Table 1.2. VI.
