In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity. Power is related to other quantities; for example, the power … Visa mer Power is the rate with respect to time at which work is done; it is the time derivative of work: If a constant force F is applied throughout a distance x, the work done is defined as If instead the force is … Visa mer The dimension of power is energy divided by time. In the International System of Units (SI), the unit of power is the watt (W), which is equal to one joule per second. Other common and … Visa mer Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object's velocity, or the product of a torque on a shaft and the shaft's angular velocity. Mechanical power is … Visa mer As a simple example, burning one kilogram of coal releases much more energy than detonating a kilogram of TNT, but because the TNT reaction releases energy much more … Visa mer Power is related to intensity at a radius $${\displaystyle r}$$; the power emitted by a source can be written as: Visa mer • Simple machines • Orders of magnitude (power) • Pulsed power • Intensity – in the radiative sense, power per area Visa mer WebbThe reactive power Q in volt-amps reactive (VAR) is equal to the voltage V in volts (V) times the current I in amps (A) time the sine of the complex power phase angle (φ): Q (VAR) = V (V) × I (A) × sin φ. The power factor (FP) is equal to the absolute value of the cosine of the complex power phase angle (φ): PF = cos φ Energy & power ... mount vernon indiana chamber of commerceWebb545.7 watts. Answer: b) 745.7 watts. Explanation: Horsepower is used to define the power delivered by a machine, and it is approximately equal to 745.7 watts. 4. Define average power.
