Q5. Create three RL circuits as seen below (or figure out copy/paste, or look at built in circuits). Make sure each graph has its own scope with just current showing. Calculate the impedance from each inductor. In the space below the graph, describe the relationship between inductance and current, assuming the frequency of the A/C source remains constant. Explain this relationship using the equation of impedance for inductor, noting how the change in L affects the Z equation. The results show that if the inductance increases then the current will decrease this means they have an indirect relationship. I =E/Z and where t if Lt Z(1H) = 100 +502 < -90° 100 Z(400mH) = 100 + 201 <-90° 80HZ 1H = Z120mH) = 100 + 10.1 0<-909| 100 w Imax(144= Vs/(100 +502 < -90°) 80HZ 400mH Imax[400mH = Vs/(100 +201 <-90°) Imax/20mH = Vs/(100 +10.12<-90°) 100 WW 80HZ 20mH Q6. Right click the graphs and select the option to add voltage to each graph. What is the relationship between the graphs of the current and voltages (as inductance increases, what happens to peak voltage and current)? How is that explained by the mnemonic CIVIL? Calculate the source phase shift for the 1H inductor circuit, and verify using the oscilloscope screen. Vmax(16) Vmax(400mH) Vmax(20m).

Z@30H2 = Z@80Hz = Z@200Hz = How does frequency affect the impedance of an inductor? How does this show up on the graphs of current? View just the voltage from the A/C source and the inductor from the 80Hz RL circuit on the scope. What is the phase shift between these two?

In a few years back, the human resource management has been redefining, but these changes are even more clear during the Covid-19 pandemic. Explain why? Please also explain clearly and clarify each work done. Please also give a few examples for a better interpretation. Longer explanation is better. Thank you so much for your help. Also, I do prefer typing rather than handwriting.
