Why Power factor becomes less lagging when capacitor is switched on?
Because capacitor withdraw leading current from source and net resultant become less lagging.
What is the condition for zero voltage regulation of a single phase transformer?
zero volatge regulation means the terminal volatge of transformer at full load on a given power factor become equal to the rated teriminal volatge of transformer , it happens only for leading power factor in transformer
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.
Why does the terminal voltage increase in leading load?
due to decrease in power factor
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.
Why did melaka became the leading power in the region?
because chief keef thought it was a true sosa . bang bang .
How did Rome become a great power?
Rome became the leading power of the Mediterranean world by conquest of Carthage, the former leading power.
Which helped England to become an industrial and commercial power?
One of the leading factors that led England to become and industrial and commercial power is timing. England had a head start over the rest of the world because they were acquainted with power much sooner.
What three factors enabled the United States to become the worlds leading industrial power by the 1920's?
industrialization and technology

They had warriors who became nobles who ruled and because the first kings of the greeks.
How did Andrew carnegie influence us business and turn the us economy?
His steelworks helped the united states become the world's leading industrial power.
How did the United States rise to become the leading industrial nation and economic power in the world during the 19th century?
I have no clue
What period did Rome become a major power in the Mediterranean region?
Soon after the defeat of Carthage during the Third Punic War in 146 BC.
Why Power factor becomes less lagging when capacitor is switched on?
Because capacitor withdraw leading current from source and net resultant become less lagging.
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'.
