EXPERIMENT PROCEDURE: Connect the parallel RLC circuit shown above and use the multimeter to measure all the currents in the circuit and record the values in the table below. To measure the phase shift of Ic, IL, and I, add a 1002 resistor in series with the component where you want to find the angle, and use the oscilloscope to compare the phase shift between E and the voltage across the 1002 resistor. Make sure that one end of the 1002 resistor is connected to ground. RESULTS: IR(rms) OR Ic(rms) ILurms) OL I (rms) 0° ASSIGNMENT: Calculate I, Ir, Ic, and IL (magnitude and angle in rms) using theoretical equations then compare with the measured values (Use E(rms) = 2.83VZ0° ).

EXPERIMENT PROCEDURE:
Connect the parallel RLC circuit shown above and use the multimeter to measure all the currents
in the circuit and record the values in the table below. To measure the phase shift of Ic, IL, and I,
add a 1002 resistor in series with the component where you want to find the angle, and use the
oscilloscope to compare the phase shift between E and the voltage across the 1002 resistor.
Make sure that one end of the 1002 resistor is connected to ground.
