Why does reactive power affect voltage? - Electrical Engineering Stack

Why is the power factor always 0.8?

WebThe lagging power factor is mainly caused due to inductive effect in the circuit. A circuit having a lagging power factor is considered to consume reactive power. If the current drawn by the circuit lags the supply voltage, then the power factor is lagging. Figure- Voltage and current phasor diagram of lagging power factor load Leading and lagging current are phenomena that occur as a result of alternating current. In a circuit with alternating current, the value of voltage and current vary sinusoidally. In this type of circuit, the terms lead, lag, and in phase are used to describe current with reference to voltage. Current is in phase with voltage when there is no phase shift between the sinusoids describing their time varying beh… christchurch station ukWebReactive Power can best be described as the quantity of “unused” power that is developed by reactive components in an AC circuit or system.
