SUMMARY
Reactance, resistance, and impedance are fundamental concepts in electrical engineering. Resistance is represented on the horizontal axis of an impedance phasor diagram, indicating a zero-degree phase angle between voltage and current. Reactance, shown on the vertical axis, represents the phase difference of either 90 degrees (capacitors) or 270 degrees (inductors). Impedance is the vector sum of resistance and reactance, combining both elements into a single measurement.
