# What isapparent power

Apparent power is the total power required for any system while active power or real power is the power that is actually used for a particular load. This can be seen in the operation of computers, lightbulbs, and production systems where not all the available power is used.

## FAQ about Apparent Power

### What is Apparent Power?

Apparent power is the total amount of power that is required to operate a device or a system. It is important to note that this is not the same as the actual power that is used by the device or system. Apparent power is a combination of two different types of power, reactive power and active power.

### What is Reactive Power?

Reactive power is the power that is used to maintain the electric and magnetic fields in devices and systems that use alternating current (AC). This power is used to keep devices and systems running efficiently, but it does not contribute to the usable work that the device or system is producing. Reactive power is necessary for some devices and systems, but it is not used for all devices and systems.

### What is Active Power?

Active power is the power that is actually used by a device or system to produce the intended work. This power is what is measured by power meters and is what is billed by power companies. Active power is also known as real power or true power.

## What You Need to Know About Apparent Power

It is essential to understand the concept of apparent power if you want to ensure that you are using power efficiently or if you are designing and building systems that rely on electrical power. Here are some key things that you need to know about apparent power:

### Power Factor

Power factor is a measure of how efficiently a device or system is using power. A high power factor means that a device or system is using power efficiently, while a low power factor means that the device or system is wasting power. The power factor is calculated by dividing the active power by the apparent power.

### Measuring Apparent Power

Apparent power is measured in volt-amperes (VA). This is different from active power, which is measured in watts (W). To measure apparent power, you need to use a special meter called an AC power meter. This meter measures both the voltage and current that is flowing through a device or system and calculates the apparent power.

### Using Apparent Power Efficiently

To use apparent power efficiently, you need to ensure that your devices and systems have a high power factor. This can be achieved by designing devices and systems that use power more efficiently or by adding power factor correction equipment to existing devices and systems.

In As a result, understanding the concept of apparent power is essential if you want to use electrical power efficiently. By understanding the difference between active power and reactive power, and by measuring and managing the total amount of power that is required to operate a device or system, you can ensure that you are using power efficiently and effectively.
