a) [5 pts] The frequency of the source voltage in the circuit is adjusted until ig is in phase with vg. What is
the value of oo in radians per second? Show calculations in the report.
b) [5 pts] If vg = 45 cosoot V (where o is the frequency found in [a]), what is the steady-state expression for
Vo? Show calculations in the report.
c) [10 pts] Simulate the circuit in Multisim using the frequency found in [a] and verify the total impedance,
Ig and Vo. Add the expressions to find the Total impedance and Io as explained in question 1. When
finding Vo use the Differential Voltage probe and place the + and - probes as shown below (note that
only that part of the circuit is shown below.) Double click on the + probe to open the properties window.
Change the RefDes to Vo and select Show RefDes. This will display the name of the probe as Vo on the
