The DC power supply to a heating element in an immersion heater system has malfunctioned. You decide to design a diode regulator using an existing unregulated AC supply as shown in figure Q1b. The unregulated AC supply can be set to any voltage required. The faulty DC power supply is rated at 110 V and the element has a resistance of 25 Ω.
Using the information provided, determine the supply peak voltage required and the capacitance needed for a ripple voltage of 10% of the supply voltage, Vs.
V = 60 Hz
Heating element: E
