Angle notation can easily describe leading and lagging current: . [1] In this equation, the value of theta is the important factor for leading and lagging current. As mentioned in the introduction above, leading or lagging current represents a time shift between the current and voltage sine curves, which is represented by the angle by which the curve is ahead or behind of where it would be ...
Capacitive loads are leading (current leads voltage), and inductive loads are lagging (current lags voltage). If a purely resistive load is connected to a power supply, current and voltage will change polarity in step, the power factor will be 1, and the electrical energy flows in a single direction across the network in each cycle.

Current lagging voltage (quadrant I vector), current leading voltage (quadrant IV vector). These are all denoted in the adjacent diagram (called a power triangle). In the diagram, P is the active power, Q is the reactive power (in this case positive), S is the complex power and the length of S is the apparent power.

Economists, analysts, policymakers and investors take the economy's temperature by examining regularly released data sets called economic indicators. There are all kinds of economic indicators ...
By varying the excitation of a synchronous motor, it can be made to operate at lagging, leading and unity power factor. Excitation at which the power factor is unity is termed normal excitation voltage. [41] The magnitude of current at this excitation is minimum. [41]
Parabolic Stop and Reverse (Parabolic SAR) is a popular leading trend-following indicator. These indicators have three primary functions. First, they attempt to alert the technician to a ...
