Question 5 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.

Q1) What is current in terms of charge? a) Current is measured 2A in a DC circuit * How much charge is involved in the process? * How many electrons are involved in the process? * The voltage source of this current is 12 Volts. What is the power produced by the source?

How is concept of voltage in electrical circuits is related to the concept of energy
