If the electric circuit is purely resistive, that is, a configuration of resistors only connected to a battery; the source energy continually gets dissipated entirely in the form of heat. This is known as the heating effect of electric current.
Temperature effects. Ohm's law has sometimes been stated as, for a conductor in a given state, the electromotive force is proportional to the current produced.. That is, that the resistance, the ratio of the applied electromotive force (or voltage) to the current, does not vary with the current strength ..
