And again, V= IR. With a current of 14 amps, a wire resistance of .16 ohms
you get a voltage loss of 2.2 Volts. Now put in a current of zero, and what
do you get? Voltage loss of Zero. And it has meaning, with no current
flowing the voltage loss is zero, we have the full supply voltage at the far
end of wire. Note: No division by zero was done here, no electrons were
harmed either.

Did you consider that if the heater is 100 feet from the power source,
there's 200 feet of wire?
