WebFeb 14, 2024 · In an AC circuit, there may be a phase difference ($\phi$) between voltage and current. The term cos $\phi$ is called the power factor of the circuit. When the given circuit is inductive , then the current lags behind the voltage and the power factor is termed as lagging power factor. WebSuch a set of conductors, a capacitor, essentially opposes changes in voltage, or potential difference, across its plates. A capacitor in a circuit retards current flow by causing the alternating voltage to lag behind the alternating current, a relationship in contrast to that caused by an inductor. http://hyperphysics.phy-astr.gsu.edu/hbase/electric/phase.html fishlake lodge and resort

WebJan 6, 2024 · The term ‘lagging power factor’ is used where the load current lags behind the supply voltage. It is a property of an electrical circuit that signifies that the load current is inductive. For capacitive circuits, where the load current leads the supply voltage, the term ‘leading power factor’ is used. WebThis results in a voltage wave that is 90° out of phase with the current wave. Looking at the graph, the voltage wave seems to have a “head start” on the current wave; the voltage “leads” the current and the current “lags” behind the voltage.
