Apparent power, a crucial electrical concept, is calculated by multiplying the voltage and current in a circuit. For single-phase systems, the calculation is straightforward: apparent power (in kilovolt-amperes) equals voltage (in volts) multiplied by current (in amperes), then divided by 1000. Three-phase systems, however, require an additional factor. For balanced three-phase loads, the calculation becomes voltage multiplied by current multiplied by the square root of 3, then divided by 1000. For unbalanced three-phase loads, each phase’s apparent power must be calculated separately using the single-phase method, and then the three individual apparent power values are added together. For instance, a single-phase circuit with 240 volts and 10 amps yields 2.4 kVA, while a balanced three-phase circuit at 480 volts and 10 amps results in 8.3 kVA.
