Replace the diodes of Procedure 3 with a 1 N4732 Zener diode, keeping the cathode connected to ground. Fig. E1.S2 R1=1.0( KΩ), D1 = 1N4732 Simulation-S2 Simulate the I-V characteristic curve for the 1 N4732 Zener diode under both forward and reverse bias conditions. Change the power supply voltage Vbias 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 Vbias is changing. A DC sweep should be performed using LTspice. Deliverable Submit your plots of the I-V curve and the LTspice schematic files. Question-S2 (a) Using the I-V curve from LTspice, compute a value for the Zener resistance R2of the diode in its breakdown region. Similarly, compute a value for the forward (on) resistance Rf of the diode in its forward bias region. The easiest way to do this for both regions is to identify two strategic (I,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 1 N4732 Zener diode is quoted at 1.0Watt. 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.
