A twobranch parallel RC circuit has a total current of 5mA T
A two-branch parallel RC circuit has a total current of 5mA. The circuit\'s capacitive reactance is 2 k. The aplied voltage is 5 V. Determine the following circuit parameters: R, Ic, Ir, Z, and .
Solution
capacitor current ic=5/(2*10^3)=2.5 mamps
resistor current=5-2.5=2.5 mamps
R=5/(2.5*10^-3)=2kohms
z=[(2*10^3*-j2*10^3)/(2*10^3-j2*10^3)]=(1000-j1000) ohms=1414.2<-45 ohms
