What is wattless current ? Explain the help of a power factor.
Answers
Answer:
A Wattless Current can be defined in following way: The current in an AC circuit is said to be Wattless Current when the average power consumed in such circuit corresponds to Zero.Such current is also called as Idle Current
Answer:
Wattless current is also known as reactive current, which is a type of AC current that flows through an inductor or capacitor without contributing to real power.
Explanation:
Wattless current is also known as reactive current, which is a type of AC current that flows through an inductor or capacitor without contributing to real power. This is because reactive power is oscillating power that is stored in the inductive or capacitive elements of a circuit and is exchanged between the source and the load during each cycle of AC. Unlike real power, which is converted into useful work, reactive power is dissipated as heat within the circuit.
The power factor is the ratio of real power to apparent power and is represented by a value between 0 and 1. A high power factor means that the reactive power component of the circuit is low, which is desirable as it means that more of the power being supplied is being used effectively to do useful work. A low power factor indicates that there is a significant amount of reactive power in the circuit, which can lead to voltage drops, overheating, and inefficiencies in the power system.
Therefore, it is essential to maintain a high power factor in electrical systems to ensure that the power being supplied is used efficiently and effectively. This can be achieved by using power factor correction devices, such as capacitors or inductors, to counteract the effects of reactive power in the circuit and increase the power factor.
