3. For the circuit above, determine the following (express all answers in phasor form):

4. X_C
5. Z_eq
6. I_T
7. _R1
8. I_C1

• Construct the circuit with MultiSIM using a 5% tolerance for the resistor and the capacitor. Adjust the frequency according to the table below and obtain measurements from MultiSIM using AC Analysis and express in polar form.

  Frequency	IT	IR1	IC1
  100 Hz
  500 Hz
  1000 Hz
  1500 Hz
  10000 Hz
  20000 Hz

• Discuss the following:
  1. Describe the relationship between the frequency and I_T.
  2. What effect does frequency have on Z_eq?
  3. How could the circuit be modified to bring the phase angle closer to 0^○?
  4. How could the circuit be modified to bring the phase angle closer to -90^○?
