Receptor exposure and mAs have what relationship

When kVp is decreased by 15%, how should mAs be changed in order to maintain the same overall receptor exposure?

To obtain 20 mAs using the 400 mA station, use an exposure time of         second:

Which of the following statements describes the relationship between kilovoltage peak (kVp) and beam intensity?

The dose a patient recieves during a diagnositic exposure is directly proportional to the:1) mAs employed2) kVp employed3) Focal spot size selected

Which of the following exposure settings will provide a value of 40 mAs?

With an 80-kVp x-ray beam doubling the mA would double the number of which photons in the primary x-ray beam?

The factor that determines the total quantity of x-rays produced in a beam is the:

If 1 ampere equals a flow of 6.3 × 1018 electrons per second, how many electrons flow from cathode to anode in 1 milliampere?

If you want a 10 mAs exposure and have selected the 50 mA station, what time in seconds is needed to produce the desired mAs? (Use decimal notation, and a leading zero if necessary.)
