võimsusmõõtme
Võimsusmõõtme, literally translated as "unit of power", is the measurement of the rate at which work is performed or energy is transferred. In physics, power is defined as the derivative of work with respect to time, or equivalently as the rate of change of energy over time. The concept is essential for describing how quickly energy can be utilized or generated in mechanical, electrical, thermal, or other systems.
In the International System of Units (SI) the fundamental unit of power is the watt, symbol W.
Other units have been historically important. The mechanical horsepower, defined as 550 foot‑pounds per second or
Power measurement is crucial across physics, engineering, and everyday life. From designing motors and generators to
