Module 4 Electric Current-The Battery | Science 111
There is an electric field in conductors that causes electrons to drift in the direction opposite to the field. The drift velocity is the average velocity of these free charges. The expression for the relationship between the current and drift velocity can be obtained by considering the number of free charges in a segment of wire.

Defining the EMF of a Battery in Simple Words
There isn''t any battery in existence that is fully efficient in its transfer of power to an external circuit. Some of it will inevitably be dissipated. This concept is reminiscent of the laws of thermodynamics, which emphasize that no mechanical machine can utilize and convert an input into an output without the expenditure of a marginal amount of energy on itself.
electrostatics
If you had, say, a resistor in your circuit, then there is an electric field inside the resistor driving the current, so those surfaces orthogonal to the electric field cross through the resistor, and the energy from the battery (or capacitor) actually flows along these
