Refer to the diagram below. Calculate the total inductive reactance and impedance. Determine the source voltage if the current in the circuit is 400 uA. Using the circuit below, calculate the total inductive reactance, phase angle and amount of voltage across V_Out.

Solution

3) f=20khz

w=2*3.14*f=2*3.14*20*10^3=125663.7 rad/sec

xl=jwl=j125663.7*200*10^-3=j25132.74 ohms

400*10^-6=vs/(20,000+j25132.74)

vs=400*10^-6(20,000+j25132.74)=12.84<51.48 volts

4)

f=100 khz

w=2*3.14*f=2*3.14*100*10^3=628318.5 rad/sec

xl=jwl=j628318.5*15*10^-3=j9424.775 ohms

xl=9424.775<90 ohms

vout=10,000(10<0/(10,000+j9424.775))

vout=7.277<-43.3 volts.
