How do you calculate KVA using volts and amps?

To calculate KVA (kilovolt-amperes), you use the formula that relates voltage and current in a straightforward manner. The correct approach is to multiply the volts by the amps to find the apparent power in volt-amperes (VA). Since KVA represents this value in thousands, you divide the product of volts and amps by 1000.

The formula is:

KVA = (Volts x Amps) / 1000

This formula accurately derives the kilovolt-ampere rating, which is essential for understanding the capacity of electrical systems. Using this approach ensures that the values are in the right units and converted appropriately to match the KVA measurement.

Other choices present different calculations that do not conform to the standard method utilized in electrical engineering for determining KVA. For example, attempting to add volts and amps or dividing volts by amps does not yield a result relevant to KVA; these methods do not represent a calculation of apparent power.
