Questions:
1.
Construct a Phasor Diagram to represent the source current and the branch currents, I_{R}, I_{C,} and I_{L} through the resistor, capacitor, and the inductor. The diagram does not need to be drawn to scale. However, the values of the items represented must be included in the diagram.
2. Did you notice any interesting feature in the lab exercise with regard to the two different frequencies chosen for the experiment?
3. In the Multisim simulation, change the frequency of the source to be between 725Hz to 735 Hz (in increments of 2 Hz) and record the inductor and the capacitor currents.
Frequency, Hz 
I_{R},mA 
I_{C}, mA 
I_{L}, mA
