Main breaker/switch

Double blade, single throw

Fuses

Keeps circuit from overheating from excessive amperage

Autotransformer

Changes voltage supplied to primary of the transformer, which provides various kv for tube

Pre reading kV meter

Indicate kV before exposure is made

Another name for rheostat

Variable resistor

Filament Ammeter

Connected in series

Measures filament current

Filament Transformer

Step down transformer

What does Filament transformer do

Reduces current and voltage to the.x ray tube

Rectifier

Changes AC supplies to transformer to DC

What effect does adjusting the filament control have on the production of x-rays?

Controls the quantity

Electrical devices that allow current to flow in only one direction are called:

rectifiers

In which portion of the x-ray circuit is a step-down transformer located?

Primary side (filament circuit)

When the radiographer selects kilovoltage on the control panel, which device is adjusted?

autotransformer 

What device would be used when the mA is set on the control panel

rheostat

What determines the quantity of electrons that will be accelerated across the x ray tube

heating of the filament 

Rheostat

controls filament heating

line voltage compensator

Adjusts for variations in incoming line voltage so the machine receives a stable supply.

Autotransformer

Selects the kVp by adjusting the voltage sent to the primary side of the high-voltage transformer

Quantity of electrons (mA) is controlled by:

filament heating/ rheostat

What supplies the heating current for the filament of the x rat tube

Low voltage/ filament circuit

KV is place before or after the Autotransformer

after

Current is selected through

Rheostate

What type if nitro drives the rotating anode

Induction

What changes the AC to supplied to the transformer to DC

Rectifier

How are the mA meters connected

In series

Portion of the circuit where it is stepped up by a ration 500:1 or 1000;1

High voltage/ secondary
