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 ...
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 ...
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 ...
For example, a project can be completed faster by increasing budget or cutting scope. Similarly, increasing scope may require equivalent increases in budget and schedule. Cutting budget without adjusting schedule or scope will lead to lower quality. "Good, fast, cheap. Choose two."
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]
A lead–lag compensator is a component in a control system that improves an undesirable frequency response in a feedback and control system. ... For example ...
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.
Usually, it is done by conditioning the input or the output to that system. There are three types of compensators: lag, lead and lag-lead compensators. Adjusting a control system in order to improve its performance might lead to unexpected behaviour (e.g., poor stability or even instability by increasing the gain value).
