The main power switch is found on what circuit?

What devices change alternating to direct current?

What parts does the cathode include?

Electromagnetic theory was developed in the late 1800s by what person?

The rate of flow of electrons passing through the x-ray tube during an exposure is

What is the primary purpose of the step-down transformer?

Prepping the rotor but not making an exposure on a regular basis is related to tube damage or failure.

In addition to the oil surrounding the tube, mechanical fans help to eliminate the heat produced during x-ray production

What parts does the anode include?

The step-down transformer is found on what circuit?

Why is the focusing cup able to keep the electrons together

The primary side of the high-voltage transformer is found on what circuit?

The effective focal spot is smaller than the actual focal spot because the face of the anode is angled.

AEC controls the ________________ of radiation reaching the image receptor.

The motor that turns the anode operates through what type of induction?

What is purpose of the filament circuit?

With a rotating anode, the focal spot becomes a focal, _______?

1. To produce x-rays, a cloud of electrons are necessary and the cathode must have a strong positive charge.

The stator is made up of electromagnets
