The Circuit 156

The Circit 156

QuestionAnswer
Produces electrons through a chemical reaction, stores an electric charge long term, and provides an electric potential Battery
Temporarily stores an electric charge Capacitor
A “one-way valve” device; allows electrons to flow in only one direction Diode
Inhibits the flow of electrons, thereby precisely regulating the flow of electricity through that part of the circuit where it is placed Resistor
A ________ is simply an adjustable or variable form of resistor Rheostat
Emergency devices that break or open the circuit if there is a sudden surge of electricity to the circuit or device Protective Devices (Fuses, Circuit Breakers)
A device that opens a circuit (breaks the pathway) Switch
A device that can increase or decrease voltage by a predetermined amount Transformer
Devices that convert electrical energy to mechanical energy through electromagnetic induction Electric Motors
Transformers increase or decrease voltage (or current) through- Electromagnetic Induction
A _______ transformer increases voltage and decreases current Step-Up
A __________ transformer decreases voltage and increases current Step-Down
The change in voltage and current is an- Inverse Relationship
Autotransformers operate on the principle of- Self-Induction
An Autotransformer has- Only One coil of wire around a central magnetic core
Both a Step-Up/Step-Down Transformer operates on the principle of- Mutual Induction
Both Step-Up and Step-Down Transformers have- Two coils of wire (First has fewer coils, Second has more coils)
Circuit Breakers- Protect against short circuits and electric shock
An on-off switch for the unit connected to the facility’s power supply Main Power Switch
Line Compensator- A device usually wired to the autotransformer that automatically adjusts the power supplied to the x-ray machine to 220 volts
Autotransformer- An adjustable transformer controlled by the kilovolt peak (kVp) selector on the operating console
mA meter- A device placed in the secondary circuit that monitors x-ray tube current
Rectifier- Converts AC to DC current
The Secondary Circuit Ends at the? Anode part of the x-ray tube
There are 2________ , one for the small focal spot and one for the large focal spot Filaments
Rheostat- A variable resistor controlled by the mA selector on the operating console
The ________ Receives power and increases the voltage Primary Circuit
The ________ Rectifies current from AC to DC so that electrons in tube only flow one way Secondary Circuit
The _________ Supplies low voltage, higher current to heat the filament Filament Circuit

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
