of a current is as follows:

       The strength of a current is the quantity of electricity which flows past any point of the circuit in one second.

       Example.--If, during 10 seconds, 25 coulombs of electricity flow through a circuit, then the average strength of the current during that time is 21/2 coulombs per second, or 21/2 amperes.34

       Voltage Drop in an Electric Circuit.--A difference of potential exists between any two points on a conductor through which a cur-

       rent is flowing on account of the resistance offered to the current by the conductor.

       For instance, in the electrical circuit shown in fig. 39, the potential at the point a is higher than that at m, that at m higher than that
