How Much Resistance Should a Hot Water Heater

In order to find the resistance of the heater element from the above described section, we must algebraically modify the formula to read (r = v/a). Since we know that the hot water electrical circuit feeds 220 VAC to the 16 ampere heating element the resistance of that element is equal to 13.75 ohms. We can round that number up to 14 ohms.
