reaalteho
Reaalteho is a term used in economics and engineering to describe the concept of actual power consumption or expenditure. It contrasts with apparent power, which is the total power delivered in an alternating current (AC) circuit, regardless of its usefulness. Reaalteho represents the power that is actually converted into useful work, such as heat, light, or mechanical motion.
In AC circuits, the difference between apparent power and reaalteho arises due to reactive components like
The ratio of reaalteho to apparent power is known as the power factor. A power factor close
