You must knew there's a sinusoidal wave form for both voltage nd current. That wave form is drawn between voltage/current nd phase angle. Unity: phase angle of voltage nd current matches, irrespective of magnitude leading: phase angle of current leads voltage by an angle lagging: phase angle of voltage leads current or current lags voltage by an angle
AnswerThe terms, 'leading' and 'lagging' apply to a.c. loads. 'Leading' means that the load current leads the supply voltage, whereas 'lagging' means that the load current lags the supply voltage. 'Leading' currents occur in capacitive loads, whereas 'lagging' currents occur in inductive loads.
'Leading' and 'lagging' refers to what the current is doing, relative to the voltage, never the other way around.
Leading load is better as the losses are less in this case.
Because capacitor withdraw leading current from source and net resultant become less lagging.
underdampedAnswerA lagging power factor describes a situation in which the load current is lagging the supply voltage. This describes an inductive load, such as a motor, etc.
A lagging power factor is caused by inductive reactance, which is composed of resistance and inductance -- and the resistance component lowers the supply volts. A leading power factor provides capacitive reactance that actually helps improve source voltage -- this helps motor loads run cooler.
Power Factor is the ratio of true vs apparent power, and comes into play with a reactive (inductive or capacitive) load. A purely resistive load, such as a light bulb or toaster, will have a power factor of 1 because the current is in phase with the voltage. An inductive load, however, such as a motor, will have a power factor less than 1 because the current lags the voltage. You could also have a capacitive load, with a power factor less than 1, but in this case the current leads the voltage.AnswerThe terms, 'leading' and 'lagging' refer to whether a circuit's load current is leading or lagging the supply voltage. Current will 'lead' in resistive-capacitive (R-C) circuits, and 'lag' in resistive-inductive (R-L) circuits. So, a 'leading power factor' indicates a leading current, and applies to R-C circuits, while a 'lagging power factor' indicates a lagging current, and applies to R-L circuits.
For capacitive reactance, current leads voltage. In an "ideal" circut, the leading phase angle would be 90 degrees, but this does not happen in practice due to resistance. For inductive reactance, current lags voltage. In an "ideal" circut, the lagging phase angle would be 90 degrees, but this does not happen in practice due to resistance.
The lagging strand.
The terms, 'leading' and 'lagging' refer to what the load current is doing, relative to the supply voltage (Phase difference) -never the other way around. If the current is leading the voltage, then the power factor is 'leading'; if the current is lagging the voltage, then the power factor is 'lagging'.
ssb protein bind to the lagging strand as leading strand is invovled in dna replication and lagging strand is invovled in okazaki fragment formation
the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction
One is known as the Leading strand, and the other is known as the Lagging strand.
when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.
It's always the current that determines 'leading' or 'lagging' -i.e. the angle by which the current leads or lags the voltage.
the leading strand is synthesized in the same direction as the movement of the replication fork, and the lagging strand is synthesized in the opposite direction
Because capacitor withdraw leading current from source and net resultant become less lagging.
The lagging strand is called the lagging strand because, unlike the leading strand, DNA polymerase can not replicate in a 5' to 3' uninterrupted flow on this strand. Remember, DNA has two strands that run ANTIPARALLEL, one to the other; in other words they run in opposite directions.
By definition, the terms 'leading' and 'lagging' refer to what the load current is doing with respect to the supply voltage. So, for a 'lagging power factor', it is the current that is lagging.
The terms, 'lagging' and 'leading', describe the relationship between a circuit's load current and supply voltage. They describe whether the load current waveform is leading or lagging the supply voltage -always the current, never the voltage. Inductive loads always cause the current to lag the supply voltage, whereas capacitive loads always cause the current to lead the supply voltage.
