Description : What is the advantage of high power factor?

Answer : Reduced copper losses Smaller conductor size Improve voltage regulation Increase system capability Less energy bill

Description : Can you have a power factor greater than 1?

Answer : We cannot have power factor greater than 1. As it is a measure of cosine of angle between voltage and current.
