Regarding factors affecting X-ray emission:
a. The tube voltage affects the maximum energy of Bremsstrahlung radiation
b. Due to inherent tube filtration, the maximum energy of photons measured in keV is slightly lower than the tube potential in kV
c. Beam filtration affects both the quantity and quality of the X-ray beam
d. Increasing peak kV (kVp) increases the quantity and quality of the emitted X-ray beam
e. Increasing the tube current decreases the half-value layer (HVL) of the beam
