What is letter L?

primary circuit

What is letter M?

secondary circuit

What is letter N?

filament circuit

what does a line voltage compensator do?

monitors and adjusts the voltage going into the x-ray circuit, keeps supplied power constant and consistent

what does a autotransformer do?

kVp selector, variable transformer (self induction), allows us to vary the voltage and amount of turns on the secondary side

what is the purpose of an exposure switch?

begins the exposure

what does the kVp meter do?

voltage is measured (coming out of autotransformer)

what does the step-up transformer do?

increases voltage, decreases current; takes the voltage coming from the autotransformer and steps it up to the kV range

what does the mA meter do?

measures the number of electrons from cathode to anode

what is the purpose of rectifiers?

change the flow of current from AC to DC

what does the x-ray tube do?

creates the exposure

what does the rheostat do?

vary our mA (variable resistor)

what does the step-down transformer do?

decreases voltage, increases current

what does the major kVp selector do?

allows us to change the kVp in big increments (70 to 80 to 90)

what does the minor kVp selector do?

fine tuning, change kVp 1-2, smaller increments in your kVp (change kVp from 71 to 72)

what does the main circuit breaker do?

safety, if there is a short circuit it breaks the circuit so that the power cannot get to the rest of the circuit

what is the main power switch/supply?

what we are getting out of the wall outlet
