In a purely inductive AC circuit as shown in the figure, Delta V max= 100 V The maximum current is 4.00 A at 60.0 Hz. Calculate the inductance L H At what angular frequency omega is the maximum current 3.50 A? rad/sAn AC source with Delta V max=145Vand f = 65.0Hzisconnectedbetweenpoints a and d in the figure. Calculate the maximum voltages between points a and b. Calculate the maximum voltages between points b and c. V Calculate the maximum voltages between points c and d. V Calculate the maximum voltages between points b and d.Explanation / Answer
A) Max current Imax=Vmax/(L*2*pi*f)....
L=66.3mH
B)Imax=Vmax/(L*2*pi*f)....
f=68.57 Hz.....
Imax=Vmax/srt[R^2+Xc^2].....
Xc=1/wC=37.66 ohms...
Imax=2.639 A
A) Vmax_ab=Imax*R=105.57 V
B)Vmax_bc=Imax*XL=199.416 V
C) Vmax_cd=Imax*Xc=99.38 V
D)Vmax_bd=Imax*(Xl+Xc)=298.8 V
