Decreasing the voltage decreases the force that moves the electrons along an electrical conductor BECAUSE amperage is the measurement of the number of electrons flowing in an electrical circuit.

Question

Quizplus · Accepted Answer

Both statements are true, but they describe separate and independent functions of the x-ray tube circuits. The kilovoltage controls the force or speed of electrons moving across the vacuum tube and therefore will control the penetrating ability of the x-ray beam. The amperage controls the amount of electrons available to produce x-rays and therefore the quantity of radiation produced.
