Answer / vipul dave

we try to maintain pf unity or ls 1 because in this condition reactive current is zero
app. power = root of ( act. power2 + react. power2)

Answer / kj

Only the kw is usable power. By having the power supply
power factor as close to unity as possible the amount of
current is reduced.

This means that transformers and wires for distribution can
carry more usable power without overloading.

In 110V DC supply,if a closed circuit gets open, How can we identify the voltage which is measured after the resistor(4KOhm) which is open with negative.it shows 55V +ve when measured, also the actual positive source is 55V +ve .Because there is no voltage drop in open circuit. How can we identify whether this is the voltage which is series with the resistor or the DC source direct +ve.
