7. A 3.3V 1N4728A Zener has a reverse breakdown voltage, -V₂ = -3.3 V, and a Zener 'knee' current, -Izx = -1 mA. In contrast, the 1N5226 Zener has the same reverse breakdown voltage, - Vz= -3.3 V, but a Zener 'knee' current, -Izx = -20 mA. a. In the circuit below, find the maximum resistance, R, that enables the 1N4728A Zener to regulate the voltage at 3.3 V. b. To see the effect of different Zener diodes, if a 1N5226 is used instead in the circuit below, find the maximum resistance, R, that enables the 1N5226 Zener to regulate the voltage at 3.3 V. 5V 1N4728A R Vout
