[QUOTE="anorlunda, post: 6468496, member: 455902"] Read that article that [USER=298988]@gleem[/USER] posted for you. For a dead simple example, a 100 VA UPS could power a 100 w resistance heater, but not a 100 w motor. That's why it is important. In a resistance, the imaginary power is zero, so VA and power are the same thing. That's what you are used to. The motor needs both real power (watts) and imaginary power, so the VA is the complex sum as shown in the diagram you posted in #1. [/QUOTE]
