Generation of X-Rays
... The x-ray tube current (mA) determines the x-ray flux rate (photons per square cm per second) emitted by the x-ray tube at a given kVp. mAs = mA x sec (exposure time). Low mA selections allow small focal spot size to be used, and higher mA settings require the use of large focal spot size due to ano ...

Stray voltage
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
