Circuits and phase relationships

217 views

What happens when you encounter a circuit that has resistors, inductors, and capacitors in series or parallel? How do you figure out what the phase relationship in a series/parallel reactance and resistive circuit?

That’s what phasor diagrams are for. There are phasor solvers for Matlab, and you can even do it by hand. The [appendix on phasor diagrams from Fundamentals of Circuit Analysis is online](https://onlinelibrary.wiley.com/doi/pdf/10.1002/0471758159.app1)

We know that the phase relationship is dependent on the circuit’s total impedance, Z = R + xL + xC.

You’ll have to calculate the circuit’s total resistance, total inductance, and total capacitance to calculate the total impedance. From there you can calculate your phase angle.

You can calculate a impedance phaser by using the impedance triangle. Z=sqrt(R^2 +X^2) and θ = tan^-1(X/R)

What specifically happens in any circuit depends on that specific circuit.
