what's the difference between true power and reactive power? I'm confused at these 2 terms...
True power, also known as active power, refers to the actual power used to perform work or provide energy in an electrical circuit. Reactive power, on the other hand, refers to the power absorbed and released by reactive components such as inductors and capacitors, but does not actually do any useful work.
True power is measured in watts (W) and is typically represented by the letter P. Reactive power is measured in volt-amperes reactive (VAR) and is represented by the letter Q.
True power and reactive power are related through the power factor, which is the ratio of true power to apparent power (the combination of true and reactive power). A high power factor indicates that a circuit is using more true power, whereas a low power factor indicates that a circuit is using more reactive power.
True power is essential for the proper functioning of an electrical system, as it is responsible for performing useful work. Reactive power, on the other hand, can cause inefficiencies and lead to issues such as voltage drops and overheating of equipment if not properly managed.
Devices that use true power include light bulbs, heaters, and electric motors, as they all require energy to perform work. Devices that use reactive power include transformers, fluorescent lights, and other reactive components in electrical systems.
