Which component is not found in the primary, low voltage section of the X-ray circuit?

In the primary, low voltage section of the X-ray circuit, components are designed to manage and control the lower voltage parts of the X-ray system. The primary coil of the transformer, the filament transformer, and the control panel are all essential parts of this section.

The primary coil of the transformer works on low voltage to convert incoming electricity into a usable form for the X-ray machine. The filament transformer specifically reduces the voltage supplied to the filament of the X-ray tube, enabling it to heat and produce electrons. The control panel is where the technologist sets the parameters for the X-ray exposure, working with the low voltage side of the circuit.

In contrast, the secondary coil of the step-up transformer is part of the high voltage section. This component is responsible for increasing the voltage to the necessary levels for creating X-rays and is not involved in the primary, low voltage section. Understanding this division is essential for grasping how X-ray machines operate, as it separates the mechanisms used for preparing the system for exposure from those that generate the actual X-rays.
