What is a common generator factor used in HU calculations for single-phase power?

Explanation:
The factor in HU calculations is there to account for how the power waveform used by the generator influences the heat actually deposited in the x‑ray tube. Single‑phase power delivers voltage and current that swing up and down during each cycle, so the instantaneous energy delivered to the tube is higher at the peaks than a steady, DC-like value would suggest. To convert the basic product of milliamperes, kilovolts, and time into the true heat (HU) the tube would experience, we multiply by a generator factor. For single‑phase power, this factor is about 1.35, reflecting that extra heating effect due to the ripple in the waveform. Using 1.35 helps ensure the HU more accurately represents the tube’s thermal load during exposure. The other options misestimate this heating: 0.5 would understate it, 2.0 would overstate it, and saying the generator factor isn’t used would ignore the waveform effect entirely.
