P-Use KVM in the tequtncy deman 200

part p:

apply kvl to left side loop

-50<-45+25<-45+vc=0

vc=50<-45-25<-45=25<-45 volts.

part q:

apply kcl at top node.

I delta+IL+Ib=15<0

(v/-j10)+(v-2.5Idelta)/j5+v/8=15<0

v[(1/j5)+(1/8)-(1/j10)]=15<0+(2.5*v)/(-j10*j5)

solving the above equation

v=(-300000)/(-1500+j2000)=120<53.13 volts.

I delta=(120<53.13)/(-j10)=12<143.13 amps.

IL=24.73<-50.9 amps.
