Figure 2. Power triangle. Using geometry, S can be calculated by: The cosine of angle θ is defined as the power factor (pf). The power factor is the ratio of the real ... 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… WebAs it is discussed the phase of a wave either lags or leads with that of another wave, leading corresponds that a wave is at the forefront of the other having the same amount of frequency. Whereas lagging corresponds that a wave is at the back of the other wave with the having amount of frequency. paisa bazaar cibil score company
