"WebMar 19, 2024 · 1. You are specifying (pre-determining) the power (VA) to be consumed by the load. So if you do the math the VA value can be satisfied by either 100V x 1000A = 100KVA, or by 1000V x 100A = 100KVA, (same result). So essentially you determined the current flow (at a given voltage) when you specified the VA value. Share. " - Determines the alternative current flow
