Virtual reality The argument whether or not virtua Researchpaper Help

Course Work 1 Course Work 1 Submit a report which provides answers to Questions 1 to 3. Scenario A simple power supply is operating erroneously. As a technician, you have been tasked with troubleshooting the device. Apply your knowledge in semiconductor devices and systems/circuits testing to troubleshoot the device. Learning Outcomes 1.1 and 1.2 1.1: Apply testing procedures to a range of semiconductor devices and circuits 1.2: Use relevant literature for testing semiconductor devices and circuits Describe the procedures of testing a diode and a transistor using an Ohmmeter only. Explain how to determine if the device is faulty or not? Illustrate your answer with drawings. Using block diagrams, Illustrate a complete power supply ensuring that you show sketches of all possible voltage waveforms at every stage. Describe the method(s) of testing the circuit of two possible faults in the circuit. For the circuit illustrated in figure 1, the RMS value of the supply voltage is 240V and the frequency is 50Hz. Using software, determine the output waveform of the circuit for the following conditions. For each case, calculate the ripple factor of the circuit. When c = 50uF and R = 2.5k When c = 100uF and R = 2.5k When c = 100uF and R = 100k Sketch the primary and secondary voltages of the transformer and the output voltage of the circuits in time domain showing all values. Use software to show the primary and secondary voltages of the transformer and the output voltage for all conditions stated in (a) for a working (non-faulty power supply. Demonstrated using Multisim three faulty conditions of the circuit values illustrated in figure 1, one of the faults should be a faulty diode. For those faulty conditions, show the voltage waveform at the output. Discuss your results in no more than 200 words. Figure 1
