Reactive impedance

WebMar 17, 2024 · Here, the reactive impedance of C and L elements creates a phase difference between voltage and current. This phase difference will become important later when you want to calculate real power delivered to a load component. Complex voltage and current in different circuits, as well as their phase differences. WebReactance is the energy storage and discharge from capacitors and inductors, so no power is converted to another form. Reactive loads result in ‘reactive’ power. Impedance is the overall opposition to current flow in an AC circuit, resulting in the ‘apparent’ power loss. Impedance is the Pythagorean sum of resistance and reactance.

WebSep 15, 2024 · Impedance is the combination of resistance and reactance. Components known as resistors prevent current from flowing — in other words, they have the property of resistance. Resistors are found in both AC and DC circuits, and the energy that is prevented from flowing is expelled as heat. WebMay 11, 2015 · When the phase is 90 (reactive impedance load) cos(90) is zero. (source: oru.com) The diagonal (red) line in the drawing above is VA i.e. the volt-amps applied to the load - basically it's RMS voltage x RMS current. VA is called "apparent power" and would equal the real/true power (green) should the load be totally resistive.
