In this problem, we're first asked what is a leading power factor? a leading power factor is when the load current leads a supply voltage by a certain phase angle.
00:10
A lagging power factor is when there's a phase difference between the voltage and the current, where the load current lags supply voltage.
00:19
So what is another question that's asked, what are the reasons for a low power factor? so what are a few reasons for a low power factor? one reason could be inductive loading, where certain machines draw magnetizing current and produce magnetic fields, and so they work at a lower power factor.
00:39
Another one could be variations in power loading.
00:42
So when you have a machine or system that's loaded lightly with voltage increasing and current drawn by the machine increasing, so this results in a low power factor.
00:55
And another part of this question asks, discuss about the power.

Factor improvement methods.
01:01
So there are various different power factor improvement methods.
01:04
One is a capacitor bank.
01:08
A capacitor, or a bank of a capacitor that are installed parallel to the load, will provide enough reactive power for them to function...
