In the electrical trade it has taken on the meaning that a circuit has been energized. e.g. Is the circuit for the appliance plugs hot?
<><><>
The above answer correctly addresses the normal trade interpretation of the question. But if the question was asked by a non-member of the electrical trade and is asking what it means if an appliance's plug is literally "hot" in the sense of having a hot temperature or "feeling hot to the touch", it means that the wires have become loose in the terminals inside the plug and are getting hot because of the resulting high resistance. If they are not tightened up urgently the plug and its wiring could easily catch on fire because the circuit breaker protecting the circuit may not trip to cut off the current. It may not trip because its rated tripping current may never be reached even though the plug and its flex are burning... So, if no-one is there to switch off the current and remove the plug from its socket outlet when its starts to give off smoke and a bad smell, that is the exact cause of many bad house fires every year! So at least get those wires tightened up or, better, get that old plug and its flex replaced by new ones! <><><> As always, if you are in doubt about what to do, the best advice anyone should give you is to call a licensed electrician to advise what work is needed. Before you do any work yourself,
on electrical circuits, equipment or appliances,
always use a test meter to ensure the circuit is, in fact, de-energized. IF YOU ARE NOT ALREADY SURE YOU CAN DO THIS JOB

Why would you get a shock when unplugging an appliance that is turned off - I accidentally touched the metal prong on the plug as I was unplugging it - Was this why?
The switch to the appliance is down stream from where the power comes in from the plug. Even though the appliance is turned off at the switch the appliance has electricity up to the switch. As you stated there will be voltage potential right up until the pins of the appliance become disengaged from the receptacle If you have ever noticed a three blade plug, the ground pin is longer that the hot and neutral blades. What this accomplishes is that when plugging in a device the ground is made first and when un-plugging the ground is the last to be disconnected. By holding the appliance you were at the same ground potential as the appliance. By touching the "hot" side of the plug when pulling it out you became the return path for the electricity to flow. If you had touched the neutral side of the plug when pulling it out you would have felt nothing. Be careful when removing plugs from receptacles. Always pull on the plug body and never on the appliance's cord
What is a 3 way electrical outlet plug?
Usually referred to as a 3-prong plug if we are talking about a normal home electrical issue. It is a "male plug" which fits into a "female receptacle". It has one rounded prong (Earth ground) and two spade like prongs which are "Hot" and "Neutral". The orientation of the third grounding prong insures that the Hot and Neutral are corrected properly to your appliance. This is most important when the appliance has a metal outside to reduce shock hazard. In typical installations Black wire is connected to Hot, White to Neutral and Green to Ground. Neutral and Ground are bonded together at your electric box so at any outlet the resistance (as measured by an Ohm Meter) would be quite low. -------------------------------------------------------------------------------------------------------------- A three-pin plug contains of neutral plug(left),live plug(right)and earth plug(up).The live wireis usually in the color of brown while earth wire is in the colour of green and yellow,and neutral wire is in the colour of blue.Live plug is connected with the elctrical supply.The live wire carries a voltage which drives an electric current through the electric appliance.The neutral wire offers a re-turn way for electric wire while the earth wire is a safety deivce.It protects us from electric shock in case an electric appliance is faulty.
What if the top pin on three pin plug broken in electric socket. Is it dangerous?
Not in itself. Do not plug another three prong plug in the outlet until the broken prong (round-ish) is removed from the outlet. The third prong (round-ish) on a three prong plug is the ground. It does not carry any power.Correction"It's the power return"
How does the electric lamp function using electricity?
You plug it in and it lights up. Current flowing in the filament makes it white hot, and it emits light.
What is a water heater?
It is a gas operated or electric operated appliance used to heat water.
The main purpose if the grounding pin in a three-prong plug for an appliance is to?
To avoid a shock if the hot wire in the appliance should come in contact with a metal appliance part that the user could touch.

What is an electric skillet?
It is a frying pan with a built-in electric heating element. You plug it in and the pan gets hot enough to cook with.
Is the wide part on a plug positive?
What you are refering to is a polarized plug. The wide connector forces the proper orientation in the outlet. This is so that the hot and neutral connectors in the plug, match the hot and neutral (cold) prongs on the plug. This forces a switch to operate on the "live" or hot wire. If a switch interrupted the flow of electricity in the neutral wire, the appliance would still shut off but the plug itself will remain "hot" whcih is a shock hazard. No, the wide blade on a plug is the neutral connection.
Is there a good place to buy electric hot plates in Houston, Texas?
Electric hot plates are a common small appliance that should be available everywhere. Look at discount stores such as Wal-Mart and K-Mart; they'll have what you are looking for at a reasonable price.
How does electric stove works?
Electric Stoves Work in a weird way. When you plug it in a sends a signal to the mainframe. which causes an electric volt that hits the metal causing it to get hot.
