1. The electric current; charge transmitted per unit time, measured in amperes.

   “It seems to me that ampèrage cuts just as much of a figure as voltage. In the case of static electricity we find that between the conductors of a machine, where we can get a spark of 6 or 7 inches, we will have an electro-motive force of not less than 3,000 volts, and yet there is not one of us in this room but can take that through his body without injury, because there is no ampèrage to speak of.”

   “A "Deltic" has to be handled very carefully on starting to prevent the automatic cut-out from coming into operation. The maximum permissible amperage is 2,400 and that for no more than 60sec in any one hour; 1,800 to 2,000 amps may be used if necessary for up to 5min and 1,650 to 1,800 amps for up to 30min continuously.”
