That ratio is always true but misleading when used like that because none of those values are fixed in a circuit. If I have a 1.5v AA battery connected to a 0.1 Ohm circuit (say a short length of wire) it should try and provide 15A of power. However, a single AA battery can't provide 15A of power, so the internal resistance of the battery goes up and the voltage output from the battery drops until it is within the range that the battery can provide. That's why electrical load rating is either measured in volt-amps, Watts or x amps at y volts.
