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.

What happens when lagging Power Factor changes to leading PF?
when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.
Power factor lead or lag?
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.
How do you draw phase diagram for transformer operating at load with lagging PF and leading PF?
In order to draw the phase diagram for transformer operating at load with lagging PF and leading PF, you will need to know the equation for the transformer being load free. This constant will help you with the load bearing equation of Np/Ns=Vp/Vs=Is/Ip.
In a capacitive AC circuit the current is?
leading the voltage.
What are the advntage of the leading power factor?
A leading power factor means that the current is leading the voltage. That means that in the AC cycle (50 or 60 Hz) the current reaches its peak before the voltage. The amount of phase-lead can be up to 90 degrees which means one quarter cycle, or 5 milliseconds in a 50 Hz system.
What happens when lagging Power Factor changes to leading PF?
when lagging Power Factor changes to leading PF, then the voltage across the circuit in which capacitor bank is connected, is increased.
Different types of power factor in different circuits?
The different types of power factor are: # Leading ( Due to Capacitive Circuit) # Lagging (Due to Inductive Circuit) # Unity (Due to Resistive Circuit)
What is meant by lead and lag?
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.
Leading and lagging power factor?
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'.
What do you mean lagging in electrical?
Lagging means the current is out of phase, lagging behind, the voltage. This occurs when there is inductive reactance in the circuit, such as with motors and transformers.
Which power factor is advantage lagging or leading and why?
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.
What is meant by leading and lagging pf?
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.
Where does ssb protein bind on lagging strand or on leading strand?
ssb protein bind to the lagging strand as leading strand is invovled in dna replication and lagging strand is invovled in okazaki fragment formation
What actually the power factor is?
Power factor is the cosine of the angle by which the current leads or lags the voltage in an a.c. circuit. It can also be defined as the ratio between a load's true power (expressed in watts) and its apparent power (expessed in volt amperes).Power factor is designated as 'leading' or 'lagging' which is determined by whether the current is leading or lagging the supply voltage. Leading currents are associated with resistive-capacitive circuits, whereas lagging current are associated with resistive-inductive circuits.
There is a y shaped replication fork on each side of each replication bubble what are the sides of the replication fork called?
One is known as the Leading strand, and the other is known as the Lagging strand.
Would you compare generator current to line voltage to determine if your leading or lagging?
It's always the current that determines 'leading' or 'lagging' -i.e. the angle by which the current leads or lags the voltage.
What is the saying relating lagging and leading of currents and voltages in a circuit for inductors and capacitors?
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.
