It is also known as biogenesis, reproduction, or procreation in the biological sciences. Generation is also often used synonymously with cohort in social science; under this formulation it means people within a delineated population who experience the same significant events within a given period of time.
Power in physics is the amount of work done divided by the time it takes, or the rate of work. Hereâs what that looks like in equation form: Assume you have two speedboats of equal mass, and you want to know which one will get you up to a speed of 120 miles per hour faster.
Electrical power is the rate at which electrical energy is converted to another form, such as motion, heat, or an electromagnetic field. The common symbol for power is the uppercase letter P. The standard unit is the watt,symbolized by W. In utility circuits, the kilowatt (kW) is often specified instead;1 kW = 1000 W. One watt is the power resulting from an energy dissipation, conversion, or storage process equivalent to one joule per second. When expressed in watts, power is sometimes called wattage. The wattage in a direct current (DC) circuit is equal to the product of the voltage in volts and the current in amperes.
