  2. Leading and lagging current - Wikipedia

    en.wikipedia.org/wiki/Leading_and_Lagging_Current

    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 ...

  3. Leads and lags - Wikipedia

    en.wikipedia.org/wiki/Leads_and_lags

    In the leads and lags, the premature payment for goods purchased is called a "lead," while the delayed payment is called a "lag." ... For example, now, we suppose ...

  4. Lead–lag effect - Wikipedia

    en.wikipedia.org/wiki/Leadlag_effect

    For example, economists have found that in some circumstances there is a lead-lag effect between large-capitalization and small-capitalization stock-portfolio prices. [2] (A loosely related concept is that of lead-lag compensators in control theory, but this is not generally referred to specifically as a "lead-lag effect.") [citation needed]

  5. Dependency (project management) - Wikipedia

    en.wikipedia.org/wiki/Dependency_(project...

    Both leads and lags can be applied to all 4 types of dependencies. PMBOK defines lag as "the amount of time whereby a successor activity will be delayed with respect to a predecessor activity". For example: When building two walls from a novel design, one might start the second wall 2 days after the first so that the second team can learn from ...

  6. Power factor - Wikipedia

    en.wikipedia.org/wiki/Power_factor

    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.

  7. Lead–lag compensator - Wikipedia

    en.wikipedia.org/wiki/Leadlag_compensator

    A leadlag compensator is a component in a control system that improves an undesirable frequency response in a feedback and control system. ... For example ...

  8. Aircraft compass turns - Wikipedia

    en.wikipedia.org/wiki/Aircraft_compass_turns

    The line of latitude is the maximum lead or lag a compass will have. The following explanations are for the northern hemisphere. For example, an aircraft flying at 45°N latitude making a turn to north from east or west maintaining a standard rate turn a pilot would need to roll out of the turn when the compass was 45 degrees plus one half of ...

  9. Frequency compensation - Wikipedia

    en.wikipedia.org/wiki/Frequency_compensation

    Lead compensation. Whereas dominant pole compensation places or moves poles in the open loop response, lead compensation places a zero [c] in the open loop response to cancel one of the existing poles. Leadlag compensation places both a zero and a pole in the open loop response, with the pole usually being at an open loop gain of less than one.
