What type of transformer reduces voltage in an x-ray machine?

In an x-ray machine, a step-down transformer is used to reduce voltage. This is crucial because the machine requires high voltage to create the x-ray beam, but certain components, like the filament of the x-ray tube, operate at a lower voltage. The step-down transformer works by using a coil with fewer turns of wire on the secondary side compared to the primary side, thus decreasing the voltage while increasing the current.

This reduction is essential for the operation of the filament, which needs lower voltage to heat up properly and produce electrons. The function of the step-down transformer is central to maintaining the appropriate conditions for generating x-rays safely and effectively while ensuring that the high voltage necessary for the x-ray production is achieved in the correct parts of the circuit.
