A three-phase x-ray generator can operate at a maximum of 100 kVp and 500mA at 100ms. What is the kilowatt rating of this generator?

To determine the kilowatt rating of the three-phase x-ray generator, the formula to calculate power is essential. The power (in kilowatts) can be calculated using the equation:

[

\text{Power (kW)} = \frac{\text{kVp} \times \text{mA}}{1000}

]

Given that the maximum voltage (kVp) is 100 and the current (mA) is 500, the calculation would be:

[

\text{Power (kW)} = \frac{100 , \text{kVp} \times 500 , \text{mA}}{1000}

]

This simplifies to:

[

\text{Power (kW)} = \frac{50000}{1000} = 50 , \text{kW}

]

Thus, the kilowatt rating of this generator is 50 kW. This matches the correct answer, which reflects a thorough understanding of how to calculate power output in x-ray generators. The calculation accurately aligns with the parameters provided in the question, demonstrating the relationship between voltage, current, and power in a three-phase system.
