Ripple 147

QuestionAnswer
No X-rays can be produced with ________ Alternating Current
The Negative Half of the cycle is blocked during _______ Half Wave Rectification (single phase, single pulse)
The Negative Half of the cycle is inverted during _______ Full Wave Rectification (single phase, two pulse)
The fluctuation of voltage is called Ripple
During Half Wave Rectification (single phase, single pulse), X-Rays are produced _______ Only during the positive half cycle
During Full Wave Rectification (single phase, single pulse), X-Rays are produced _______ During both halves of the cycle
When the voltage fluctuates________, this is 100% Ripple From the max all the way back to zero
When the voltage fluctuates _______, this 50 % Ripple From the max halfway back to zero
How do we reduced Ripple? By Adding Phases
A 3 phase 6 pulse generator has only ______ Ripple 13%
A 3 phase 12 pulse generator has only ______ Ripple 3%
A High Frequency generator has _____ Ripple <1%
Single & Half Wave generators have _______ Ripple 100%
Less Ripple is ________ More Efficient
Efficiency comes at the cost of _______ Increased Heat
_______ is the most efficient generator High Frequency
_______ is the least efficient generator Single & Half Wave
Generators with a _______ generate more heat Larger c number
The _________ is designed to produce the shortest possible exposure time while protecting the X-ray tube from overheating Falling Load generator
Using the selected kVp, the falling load generator begins the exposure at the _______ Highest Possible Safe mA
As the tube approaches the its heat load limits, it ______ in a process known as "falling the load” Reduces the mA
The exposure ends when the _______ Required mAs has been reached
The Falling Load Generator Maximizes tube output by Optimizing tube loading capacity SAFELY, which Minimizes exposure time
A ______ converts Mechanical (motion) energy → Electrical energy Generator
A _______ converts Electrical energy → Mechanical (motion) energy Motor
A Generator uses ______ Motion to make (generate) Electricity
A Motor uses _______ Electricity to make Motion
_______ Produces the electrical power for the X-ray tube X-Ray Generator
________ Spins the anode inside the X-ray tube Induction Motor (rotor + stator)

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.
