WebIn 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. Resistors work by converting electrical energy to heat energy; in other words, they get hot when electricity flows through them. But it's not just resistors that do this. Even a thin piece of wire will get hot if you force enough electricity through it. That's the basic idea behind incandescent lamps (old-fashioned, bulb … See more Photo: The heating element concealed inside a ceramic cooktop.
