What is a power factor in electronics?

Power factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). Apparent power, also known as demand, is the measure of the amount of power used to run machinery and equipment during a certain period.

What is the power factor of a fridge?

Inductive appliances such as electric motors, power tools, transformers, magnetic ballast type fluorescent lamps, fridges, air conditioners, etc have a power factor of approximately 0.2~0.7.

What is power factor of an appliance?

The power factor is the value of the actual (or true) power used by an appliance divided by the expected (or apparent) power–the latter being the product of the line voltage (V) and current (I). Taking a 60W light bulb as an example, the wattage represents the actual power consumed by the bulb.

What is the best power factor?

unity
The ideal power factor is unity, or one. Anything less than one means that extra power is required to achieve the actual task at hand. All current flow causes losses both in the supply and distribution system. A load with a power factor of 1.0 results in the most efficient loading of the supply.

What is the power factor of an AC circuit?

Power factor is defined as the ratio of the average power in an ac circuit to the apparent power, which is the product of the voltage and current magnitudes. Power factor (PF) has a value between zero and unity.

What is the power factor in India?

In India, if the power factor of the consumer drops below 0.85, they will be charged heavily. When the power factor is low, power and energy losses in power lines and transformers increase and the utilities include these costs in the electricity bill in the form of power factor penalty.

What is VA of fridge?

120 volts
Any refrigerator that plugs into a standard wall outlet runs at a voltage of 120 volts, which is basically the same as 125 volts or even, as you might find listed on some appliances, 115 or 110 volts.

What is kVA electricity?

A KVA is simply 1,000 volt amps. A volt is electrical pressure. An amp is electrical current. A term called apparent power (the absolute value of complex power, S) is equal to the product of the volts and amps.
