Electric Current Similar to Water Current

A perfect comparison between a closed circuit of water current and a closed circuit of electric current is made and Ohm's law is obtained in this manner and it is shown that, contrary to the current belief, existence of conduction current is not because of the existence of any electric field in the conductor, and the linear relation J = gE cannot be valid. The relaxation time (necessary for the current to reach its final speed) and the final speed (drift velocity) of the current are obtained in the above-mentioned manner, and it is shown that, contrary to what is believed at present, both of them are independent of the chosen standard unit charge (eg electron charge or coulomb) and its mass. It is also shown that, contrary to the current belief, alternating current is steady. We also prove the existence of a kind of resistance arising from the configuration of the circuit. Action mechanism of transistor is explained and a hydrodynamical analogue for it is introduced: both confirming the material presented earlier.
