Electrical Components

Question 1

What does the Step-down transformer do (low voltage)

Answer 1

Lowers voltage to prevent filament melting (john said it would increase amperage)

Question 2

Timer switch purpose

Answer 2

Variable exposure time

Question 3

mAs equation

Answer 3

mA x time (sec) = mAs (inverse relationship)

Question 4

AC

Answer 4

Alternating current (electricity)

Question 5

DC: only photon producing electricity

Answer 5

Direct current

Question 6

Converts AC to DC for the production of x-ray photons

Answer 6

Rectifier

Question 7

Which type of rectifier (1/2 wave or full wave) is more efficient?

Answer 7

Full wave, half wave only converts half of electrical input (AC)

Question 8

2 generator advantages

Answer 8

• Higher intensity and energy
• Lowers heat production

Question 9

Three Phase Generator function

Answer 9

Superimpose three waves

Question 10

High Frequency Generator advantage

Answer 10

Highest energy conservation
