Q1. You are given a 12 V DC power supply. You are expected to develop a voltage divider to achieve a voltage of nominal 5V value using a pair of resistors from the E 12 range, with the restrition that you are not expected to draw a current of more than 1 mA from the 12 V DC supply i. Develop a simple circuit showing the possible values for each resistor pair, and the range of the DC output possible...
Question 3. Unregulated supply Rz IL Vin IR Ib (a) The circuit on the right shows a series regulator connected to the output of an unregulated power supply. The transistor has B =50, and a 6 volt Zener diode is used. When the load current, Il, is 1 amp the de input voltage from the unregulated supply, Vin, is 11 volt, VBE = 1 volt and the Zener diode current, Iz, is 20 mA.

I am working on my Physics lab report where it was all about Direct Current Measurement and Ohm’s Law. We had 5 different resistors and had to construct different circuits using a power supply, volt-ohm-milliammeter (VOM) and a digital multimeter to get measurements of resistance, voltage, and current. Nominal values of resistance and tolerance Resistor Nominal Resistance (Ohms) Tolerance (Ohms) R1 680 +/- 68 R2 1000 +/- 50 R3 1500 +/- 75 R4 4700 +/- 470 R5 10,000 +/- 500...
