Yes _____ No;Explain any mismatch;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;725;727;729;731;733;735
