Why current reduces with increase in voltage in the case of Transformers.

OpenStudy (anonymous):

Please do not answer theoretically like P=vi as v increases I reduces. But answer me in terms of Electrons or charge something like that. Im looking for some practical explanation.

In a transformer, there has to be conservation of linear momentum by the electrons (because they are particles); the linear momentum could be expressed as the product of mass and velocity (or, in the case of a flow of electrons, as the product of mass per unit of time times velocity); the mass term in the linear momentum is related to the current (because if you multiply a flow of electrons times the charge of an electron, you get the current flowing into the transformer), while the velocity term is related to the voltage (because voltage relates to the potential energy and, if you equate the potential and the kinetic energy of an electron, you get voltage as a function of the square of the velocity of the electron); conservation of linear momentum in a transformer leaves two choices: either the mass flow reduces and the velocity increases (therefore current decreases and voltage increases) or the mass flow increases and the velocity decreases (therefore current increases and voltage decreases). I hope this helps

Hey thanks a lot. This is for what im looking for.
