Answer
The two main types of power in electrical systems are:
- Real Power (Active Power) - The actual power consumed and converted to useful work, measured in watts (W). This represents energy that performs actual work like running motors, heating elements, or lighting.
- Reactive Power - Power that flows back and forth between the source and reactive components (inductors, capacitors), measured in volt-amperes reactive (VAR). While it doesn't perform useful work, it's necessary for the operation of AC equipment.
The relationship between them creates apparent power, which determines the total capacity needed from power systems.
