Doubling the mA factor will result in:

Doubling the milliampere (mA) factor effectively increases the quantity of x-ray photons produced during exposure. This increase in photon quantity directly results in a greater level of exposure on the film or detector, leading to an increase in image density. Density in radiographic imaging refers to the degree of blackening on the film, which corresponds to the amount of x-ray energy that has been absorbed. Therefore, when the mA is doubled, it can be expected that the density will also double.

Additionally, the relationship between mA and density is generally linear, meaning if you double the mA, you can anticipate a doubling of the density assuming all other exposure factors remain constant. This understanding is vital for making adjustments in imaging techniques to achieve desired exposure levels and image quality.
