Transform the circuit shown into the phasor domain. Find the current in R_1.
Solution
from the source voltage w=1000 rad/sec
xl=jwl=j1000*4.7*10^-3=j4.7 ohms
xc=1/(jwc)=1/(j1000*100*10^-6)=-j10 ohms
total impedance=200+[j4.7*(100-j10)]/(100+j4.7-j10)
total impedance=(200.22+j4.7116) ohms
current through R1=5<60/(200.22+J4.7116)=0.0249<58.65 AMPS.
