WebA volt-ampere (SI symbol: V⋅A or V A, simplified as VA) is the unit for the apparent power in an electrical circuit.The apparent power equals the product of root mean square voltage (in volts) and root mean square current (in amperes). Volt-amperes are usually used for analyzing alternating current (AC) circuits. In direct current (DC) circuits, this product is … WebJan 29, 2014 · The key is that for a resistive load, the voltage and current are in phase. If the voltage and current are both \$\sin(t)\$, then then their product is given by the equality \$\sin^2(t) = 1/2 + 1/2 \sin(2t)\$. The power is a sine wave of twice the frequency, which oscillates about \$1/2\$. This is its average over time (the "mean" of the "square").
