A small doorbell transformer rated at 50-volt-amperes is equivalent to how many kVA?

To convert volt-amperes (VA) to kilovolt-amperes (kVA), you need to understand the relationship between these units. The conversion is straightforward: 1 kVA is equal to 1,000 VA.

Given that the transformer is rated at 50 volt-amperes, you can determine how many kilovolt-amperes this represents by dividing the number of volt-amperes by 1,000:

50 VA ÷ 1,000 = 0.05 kVA.

This calculation shows that a small doorbell transformer rated at 50 volt-amperes is equivalent to 0.05 kVA. Thus, the correct answer accurately reflects this conversion, providing a clear understanding of how the units relate to each other in the context of electrical measurements.
