20 Amp dimmer control?

formatting link

A water heater that maintains desired temperature by turning the applied power on and off (as opposed to continuously varying electrical voltage or current) based on temperature feedback is an example application of bang?bang control. Although the applied power switches from one discrete state to another, the water temperature will remain relatively constant due to the slow nature of temperature changes in materials. Hence, the regulated temperature is like a sliding mode of the variable structure system setup by the bang?bang controller.

Can this now be put to rest !!

Where does all the heat energy dissipated by the coil go? Think!

Yes, and absolutely 100% of the heat gets into the water. It is a HUGE mass DIRECTLY attached to the heating element via full immersion.

This isn't about a water heater.

You stupid f*ck. it isn't about the thermal mass of a tank of water, it is about the thermal mass of a heating coil in air. BIG difference.

You might come close in this lifetime, if you actually knew what the discussion was about.

You do not. You aren't even close. Go away, little girl.

Please let us know where you got your EE degree from ?

Second year EE students have to take classes on this.

Where did you go to school ??

Did you graduate ??

The amount of swearing you do, tells me you are a college drop out.

I'm done here, good luck.

Gib - He knows no physics. His "knowledge" comes from reading news and newsgroups. He is an idiot who does not know math. He can't calculate the flight time of light between planets. He tried once and went away red-faced. He is a verbal abuser. The group knows him as AlwaysWrong among many other nyms. Ignore him, if you can.

You've been warned.

You were done long before here.

Fuck off and die, you disingenuous twit.

one the water is boiling, having the heat on full power only makes more steam, it doesnt cook any faster than a slower simmer.

the goal is cooking, not thermodynamic efficiency.

when you whack it with a spoon it doesn't sound like sheet metal. and when you cut it open you find it's solid,

there's a thickish metal layer and some sort of ceraramic and the nichrome wire, with cermaic packed tightly around it,

Oh that explains everything. Your mind is firmly closed and you dont read what people actually write.

The problem is you don't get it and you don't get that you don't get it.

This "open coil in air" is entirely your own invention.

The hotplate most everyone else is dscussing an enclosed coil packed in ceramic and wrapped in steel.
