In a simple alternating current (AC) circuit consisting of a source and a linear time-invariant load, both the current and voltage are sinusoidal at the same frequency. If the load is purely resistive, the two quantities reverse their polarity at the same time. At every instant the product of voltage and current is positive or zero, the result being that the direction of energy flow does not reverse. In th… WebMar 11, 2024 · Reactive power is the portion of electricity that helps establish and sustain the electric and magnetic fields required by alternating current equipment.

WebThis phase angle of reactive opposition to current becomes critically important in circuit analysis, especially for complex AC circuits where reactance and resistance interact. It will prove beneficial to represent any component’s opposition to current in terms of complex numbers rather than scalar quantities of resistance and reactance. Review WebSimilarly, an AC circuit can consume "reactive power," given by these equations: Q = I 2 X Q = V 2 /X. X is the reactance, as in Z = R + jX. Unlike R, X can take on negative values. So, although P (real power) is always positive, Q (reactive power) may be positive or negative. The reactive power is not in the units of watts, because it is not ... WebFeb 13, 2024 · Reactive power, denoted with Q, is transferred when the current and voltage are 90 degrees out of phase. In such a case, the net energy transferred in the AC circuit equals zero, and we do not loose any real power. Reactive power never appears in DC circuits. In AC circuits, it's linked to the reactance produced by inductors and capacitors. can dementia happen in someone in their 20s
