ABSTRACT: For a given electric match resistance and wire gauge, the number of electric matches that one can fire in a single circuit, using a standard DC firing system, depends on the arrangement in which the electric matches are wired (series, parallel or series-parallel). The number of electric matches fired from a single cue can be maximized by utilizing series-parallel circuits. This is demonstrated using graphs of the amount of current that is sent through each electric match in various series and parallel combinations. This data allows one to determine the maximum number of electric matches that can be successfully fired in a single circuit.
Keywords: electric match, all fire current, cue, electrical firing, resistance
