Set-Up Replace the diodes of Procedure 3 with a 1N4732 Zener diode, keeping the cathode connected to ground. R1 me Test Zener Diode Fig. E1.4 Use the following parts: R1 = 1.0 (KO), D1 = 1N4732 Simulation Simulate the l-V characteristic curve for the 1N4732 Zener diode under both forward and reverse bias conditions. Change the power supply voltage Vous from -10 Volts to +5 Volts. Again, plot the I-V curve of the diode. The x-axis should be the voltage across the diode and the y-axis should have positive current values when the diode is forward biased. * As the supply voltage Vbia is changing, a DC sweep should be performed. Deliverable include your plots of the l-V curve and the LTspice schematic files in your report. Question-4 (a) Using the 1-V curve from LTspice, compute a value for the Zener resistance Rz of the diode in its breakdown region. Similarly, compute a value for the forward (on) resistance Re of the diode in its forward bias region. The easiest way to do this for both regions is to identify two strategic (1,V) points which define the best fit lines in these regions and then compute the inverse slopes of these lines. (b) The power rating of the 1N4732 Zener diode is quoted at 10 Watt. Calculate the maximum current that the diode can handle in the forward (on) direction and then in the reverse (Zener) direction so that the power dissipated does not exceed the 1.0-Watt limit.
