Question

4 Consider the circuit given in Figure 3. 220 ? 560 2 BZY88 Ru Volt) +12 4702 Figure 3 The load resistance Rt varies between 5600 and 10300. Using LT-SPICE find the maximum and minimum values of the output voltage as Re varies. Note1: BZY88C6V2 zener diode does not exist in the generic library of LT-SPICE, so you should add provided library file to you or construct your own library file. The model given is BZX84C6V2, not BZY88C6V2. So, we can expect some variation among your preliminary works and your experimental results Note2: When being used a voltage regulator, if the voitage across the load tries to raise then the Zener takes more current. The increase in current through the 2200 resistor causes an increase in voltage dropped across the resistor. This increase in voltage across the 2200 resistor causes the voltage across the load to remain at its correct value In a similar manner, if the voltage across the load tries to fall, then the Zener takes less current. The current through the resistor and the voltage across the resistor both falls. The voltage across the load remains at its correct value.
