Determine the capacitor and inductor voltages, Electrical Engineering

• 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

• 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.
