Which capability is associated with higher mA capacity for 3-phase/high-frequency generators?

• A. Near constant potential
• B. Higher mA capacity for short exposures
• C. Higher effective kVp
• D. Lower ripple

Answer: (B)

High-frequency/3‑phase generators can deliver a higher tube current for a brief moment because their voltage is very stable and has minimal ripple. When exposure time is short, you can push a larger current through the tube without exceeding the thermal limit, since the heat is deposited over a very short interval. In other words, the combination of stable voltage and short exposure allows a higher mA for those brief shots. The other options describe beam quality or waveform characteristics in general, but they don’t specifically explain the ability to increase mA for short exposures in these generators.
