Unformatted text preview: and VZ you are working with. The full wave rectifier from Lab 2 will be producing about 30 volts DC. The value of this resistor is not very critical as long as you have 10 20mA going through the zener diode and 1kΩ is often a good value. 4. Calculate voltage divider resistors R1 and R2. R1=________________________ R2=________________________ Calculate R1 and R2 to divide VOUT down to your zener diode voltage VZ. See Equation (1). Pick resistance values for R1 and R2 which are between 5kΩ and 100kΩ so you don’t need to worry about the power dissipation of these resistors. NOTE: for steps 3 and 4 you will have to work with standard resistor values so your currents and voltages will only approximate the desired voltages and currents. 5. Determine an initial load resistor RLOAD. RLOAD=________________________ Determine RLOAD at VOUT for an initial load current of ap...
