Experiment• Wire the circuit shown in Figure. Connect the three oscilloscope channels as shown in Figure.• Select the sinusoidal waveform. Adjust the frequency of the input voltage Vin to 10kHz. Adjust the magnitude of the input voltage Vin to 1Vpp. • Use the oscilloscope to measure magnitudes and phase angles of all voltages in the circuit (remember that Vin is the reference with 0o phase angle).• Stop the oscilloscope scanning and save data for all oscilloscope channels for possible processing in MATLAB
Report• Using the measured values draw a phasor diagram showing all currents and voltages. You will need to calculate currents from the measured voltages as oscilloscopes only measure voltages. All measured voltages are with a reference to the ground, so you may need to use MATLAB to determine the capacitor and inductor voltages. Document well all your processing and methods used.• Compare the measured values with the calculated and simulated values. Use a table for comparative display of results.• Comment on any discrepancies. • Can you determine the resistance of the inductor? Explain the method used.
Limitations: 1. Silicon transistors do not function at voltages much higher than about 1,000 volts (SiC devices can be worked as high as 3,000 volts). In difference, electron
