HELP!! POINTS WILL BE GIVEN!! SHOW ALL THE WORK, THANKS.
The circuit below is in steady state
A. Calculate the voltage across the capacitor Vc and the current through the inductor iL
B. Calculate the energy stored in the capacitor.
C. Calculate the energy stored in the inductor.
Solution
consider f=60 hertz
Xl=j2*3.14*60*2=j753.6 ohms
Xc=1/(j2*3.14*60*0.1)=-j0.02652 ohms
apply nodal analysis
(v-24)/(4*10^3)+v/(6*10^3-j0.02652)+v/(2*10^3+j753.6)=0
solving the above equation, we get
v=6.8943<10.92 volts
current flown through the inductor is Il=v/(2*10^3+j753.6)=3.225*10^-3<-9.719 amps
current flown through the capacitor is Ic=v/(6*10^3-j0.02652)=1.149*10^-3<10.92 amps
voltage across the capacitor is Vc=Ic*Xc=3.047*10^-5<-79 volts
energy stored in the capacitor is E=(1/2)*C*V^2=0.5*0.1*(3.047*10^-5<-79)^2=4.642*10^-11<-158 JOULES
ENERGY STORED IN THE INDUCTOR IS E=(1/2)*L*Il^2=0.5*2*(3.225*10^-3<-9.719)^2=1.04*10^-5<-19.438 JOULES.
