[quote=LuckyInOC]Why would they call it resistive heating if it was based low resistance?
“The mathematical equation that describes this relationship is: V = I/R where V is the potential difference measured across the resistance in units of volts; I is the current through the resistance in units of amperes and R is the resistance of the conductor in units of ohms.”
R = I/V same thing right?
If V (volts) is constant 120 volts.
and I (current in amps) is increased.
Then R (resistance) is also increased.
Your typical resistive home heater is 1500w. At 120v , it is pulling 12.5 amps or 0.10427 ohms. Whereas, a 1000w heater at 120 volts is 8.3 amps or 0.0694 ohms. More heat, more resistance – Ohm’s law. [/quote]
Uh. This is bass-ackwards and mis-quoted Wikipedia, giving the wrong equation for Ohm’s law. Wikipedia says (and every electrical engineer in the world knows) that
I = V / R.
Check the link and focus on the equation show in very large, bold type.
So, your last equations should result in a 1500 watt heater having resistance of 9.6 ohms, and a 1000 watt heater having a resistance of 14.4 ohm.
“Short circuit” is a relative term since nothing really has “0” resistance. Since it is pretty clear that you don’t know anything about practical electrical circuts (nice try changing Ohm’s law to suit your theory, though – that was bold), let me tell you that 14 ohms is pretty damn low.
Lower resistance means more current, means more heat.
Tell you what I’ll hook my dry body up to 120 volts and you hook your wet body up to 120 volts. (Wet bodies have lower resistance). We’ll see who gets hotter.
