The Friis transmission equation is used in telecommunications engineering, and gives the power received by one antenna under idealized conditions given ... more

Power is the rate at which work is done. It is equivalent to an amount of energy consumed per unit time. The same amount of work is done when carrying a ... more

The power of a point is a real number that reflects the relative distance of a given point from a given circle. It is related to the distance from the ... more

In physics, attenuation (in some contexts also called extinction) is the gradual loss in intensity of any kind of flux through a medium. For instance, dark ... more

Electric power is the rate at which electric energy is transferred by an electric circuit.

Electric power is the rate at which electric energy is transferred by an electric circuit.

Alternating current power depends on the voltage and the load resistance

Power is the rate of doing work. It is equivalent to an amount of energy consumed per unit time. The same amount of work is done when carrying a load up a ... more

Mechanical advantage is a measure of the force amplification achieved by using a tool, mechanical device or machine system. Ideally, the device preserves ... more
