This is only true for DC. For AC, you need to know the phase of the
current with respect to the voltage, or the Power Factor, to compute the
Real Current, the component of the current in phase with the line
voltage. Real current X volts DOES = power, but magnitude current
X volts is actually a meaningless number.
