A 115-volt, 2-KVA, single-phase generator operating at full load will deliver how many amperes?

Explanation:
In a single-phase system, the apparent power S equals voltage V times current I (S = V × I). A 2 KVA rating means the generator can supply 2000 volt-amperes. At 115 V, the current at full load is I = S / V = 2000 / 115 ≈ 17.39 A, which rounds to 17.4 A. Because this uses apparent power (KVA), you don’t need the power factor for the calculation.
