a) For a DC Power Supply, having a voltage of 50 V, design circuits which can give the
following output voltages:
i) 10 Volts
ii) 25 Volts
iii) 45 Volts
Draw the labelled circuit diagram for each output voltage value and show calculations for
all. Use R1 = 4.7 kQ for one of the resistance
Hint: Use voltage divider circuits, you can use any value of resistances you like.
