Question:

Finding I(t) for capacitor or inductor in series with resistance for ac circuit using complex nos.?

A resistor, a capacitor are connected in series across an ac voltage source. ext emf 2.5sin(wt+pi/3). What is the current in circuit (given R,Xc and XL)

Answer:

Iemf/Z in the steady state where ZR for a resistor Zj w L for an inductor Z-j/( w C) for a capacitor If circuit has multiple series and parallel components, you can find the equivalent impedance by combining the individual impedances the same way you do for resistance. It's not hard, but you do need to use complex math.
degree the voltage Vr in the course of the resistor R. the present interior the circuit is I Vr/R. the same contemporary flows interior the inductor and capacitor. So volts in the course of inductor I*Xl I*2*pi*f*L Volts in the course of capacitor a million I*Xc1 I/(2*pi*f*C1) Volts in the course of capacitor 2 I*Xc2 I/(2*pi*f*C2) Does that help?
