Transcribed Image Text:You are to design a simple power supply made up of recycled electrical parts to drive a motor. To simplify the
design, you can model the running motor as a load resistor. The motor is rated for 20V and draws 100mA when running.

If you were to model the running motor as a resistor what would the resistor value be?
b. The transformer has a turns ratio a = 3.75. What are the RMS and Peak values of the secondary voltage?
What is the peak voltage after the diode rectifier bridge (without C1, Zener, resistor, or load)? Draw the waveform.
d. Determine the ripple voltage (VRIPPLE) without the Zener diode in the circuit (assume the Resistor above is 1002).
Determine the part number of a suitable Zener diode to provide an output voltage of approximately 20v. (i.e. 1N4
