Question

question 20 / 40
which of the following statements describes the relationship between milliamperage (ma) and beam intensity?
beam intensity is inversely proportional to the square of the ma
beam intensity is directly proportional to the square of the ma
beam intensity is directly proportional to the ma
beam intensity is inversely proportional to the ma

Explanation:

In X - ray physics, the beam intensity is directly proportional to the milliamperage (mA). When the mA is increased, more electrons are available to strike the anode, resulting in a greater number of X - rays being produced and thus an increase in beam intensity.

Answer:

Beam intensity is directly proportional to the mA
