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.
As an example, consider a balanced three phase load consuming 36 kW at a power factor of 0.86 and line to line voltage of 400 V (VLL) : Easy enough. To find the power given current, multiply by the voltage and then the power factor to convert to W. For a three phase system multiply by three to get the total power. Personal note on the method As a rule I remember the method (not formulae) and rework it every time I do the calculation.
