circuits, in radiograph machine,

n.pl a radiograph machine contains two circuits, the low-voltage filament circuit and the high-voltage cathode-anode circuit. The low-voltage circuit uses a step-down transformer to form an electron cloud by heating up the filament. The high-voltage circuit uses a step-up transformer to increase the current enough to accelerate the electrons to the point that they create radiographic photons.
