Question

As the power factor of a circuit is increased……​

Answer 1

Answer:

As the power factor increases, the ratio of real power to apparent power , increases and approaches unity (1), while the angle θ decreases and the reactive power decreases.

Answer 2

When power factor is increased in a circuit it cause improvement in voltage,, increase load carrying capacity and decrease power loss.

To understand the question clearly, first we need to know what is power factor?

• The ratio of the actual power  that is used in an alternating circuit to the apparent power that is supplied  is called power factor.
• Power factor always carry a value between Zero and One.
• Power factor determines how effectively electricity is being used as it depends upon the load in the circuit.

Thus, increased power factor improves the voltage whereas low power factor leads to increase in current and lead to decrease in the voltage.
