100

The area actually bombarded with filament electrons.

What is the actual focal spot?

100

These devices are used to lower the current from amperes to milliamperes and increase the voltage from volts to kilovolts

What are step-up Transformers?

100
This phase permits the potential difference to drop to zero with every change in the direction of current flow.
What is Single-phase power?
100

The amount of voltage supplied from the incoming line of power to all x-ray equipment.

What is 220V?

*Also accept 200 to 240 volts

100
The charge on the focusing cup
What is negative?
200

The x-ray beam area as seen from the perspective of the patient.

What is the effective focal spot?

200

DOUBLE JEOPARDY

The process of changing alternating current to direct pulsating current.

200

Exposure timer is located in this part of the x-ray circut

What is the primary circuit?

200

This device is operated on the principle of self induction.

What is the autotransformer?

200

Driving the thermionic cloud from the cathode to the anode requires:

What is high voltage from secondary circuit?

300

Typical target angles are between _ and _, with __ being the most common angle in general purpose tubes. 

What are between 7-18 degrees and 12 degrees is the most common?

300
The process in which half of the incoming current is changed to pulsating direct current.
What is half-wave rectification?
300

This device is located in between the incoming power line and the step-down transformer.

What is the mA meter (rheostat)?

300

The direction of the flow of electrons in the x-ray tube.

What is cathode to anode?

300
A phenomenon by which more and more electrons build up in the area of the filament.
What is the space charge effect?
400

The smaller the anode angle, the _______ the effective focal spot.

What is smaller?

400
This device is constructed by connecting both the primary and secondary coils in a series instead of insulating them which allows the device to select varying amounts of voltage.
What is an autotransformer?
400

A variation of the electronic timer that monitors the current passing through the x-ray tube and terminates the exposure when the desired mAs is reached is called this and located in this circuit

What is the mAs timer and located in the secondary circuit?

400
This device is located between the incoming power line and the exposure switch.
What is the kVp control?
400

X-ray production occurs on the _______ side of the x-ray tube.

What is the anode?

500

This principle states that by angling the face of the anode target, a large actual focal spot size can be maintained, and a small effective focal spot size can be created.

What is the line-focus principle?

500

A rectifying semiconductor that is made by joining a p-type crystal with an n-type to form a p-n junction so that current flows in only one direction.

What is a diode?

500

A radiolucent device placed between the patient and the image receptor that terminates the exposure when completely filled

What is AEC ionization chamber?

500
All radiographer controls are located on this side of the x-ray circuit to protect operators from high-voltage shock hazards.
What is the low voltage side?
500
The anode assembly consists of these three parts.
What is the rotor, stator, and anode?
