question 22 / 50
which statement describes the relationship between milliamperage (ma) and beam quantity?
beam quantity is inversely proportional to ma
beam quantity is directly proportional to the square of the ma
beam quantity is directly proportional to ma
beam quantity is inversely proportional to the square of the ma

Explanation:

In X - ray production, the beam quantity (intensity of the X - ray beam) is directly related to the milliamperage (mA). When mA increases, more electrons are emitted from the cathode and strike the anode, resulting in more X - ray photons being produced. So, beam quantity is directly proportional to mA.

Answer:

Beam quantity is directly proportional to mA
