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.
A transformer cannot output more power than inputted, due to CEL (conservation of energy law). Right off the bat, it should be obvious that the secondary power, which is Isec*Vsec must equal the primary power, Ipri*Vpri, minus losses. Faraday's law, FL, relates the magnetic flux density, B, to the voltage, V, and the frequency, f. Ampere's law, AL, relates the magnetic field intensity, H, to the current, I. Also, B and H are interrelated through the permeability mu, which is analogous to Ohm's law (for magnetics).
