Is electricity wasted by leaving a disconnected 15 volt adapter plugged into an outlet?
Yes. You can tell if the adapter is warm then there is a waste of energy. It is the excitation of the transformer that is causing the heat loss.
What is the power consumtion of a light bulb that is plugged into a 110v outlet and is drawing 0.727 amp or current?
Power is calculated from volts time amps. 110V x 0.727A is 79.97 watts. Note that power is not "consumed" but rather converted to other forms of energy such as light and heat.
How many watts does it take to run a heat mat?
I don't know what exactly you mean by a "heat mat", but your question is kind of backwards. You don't run an electrical device *with* watts. You run them to *produce* watts (watts of light, watts of heat, watts of sound, etc). I believe the thing you are really asking is how many amps are required to run your device. As an example, consider a "1500 Watt heater" that is made to be plugged into a typical wall outlet in your home. The voltage in the wall is 120V, and the heater will produce 1500 watts of heat when plugged into that 120V. To calculate the amps, you divide the watts by the voltage. 1500W / 120V = 12.5A
Does anyone make a dimmer switch with an outlet?
Probably not. Dimmers must dissipate a significant amount of heat generated by the dimming process. An outlet would occupy too much room in a switchbox to allow the dimmer to cool properly. In addition, an outlet (receptacle) carries its own load which also means additional heat in the switchbox. Electrical codes require boxes to be filled only to a certain point to allow proper heat disipation.
Does leaving the switch on to a switched outlet use electricity if nothing is plugged into the outlet?
Actually curent or voltage that passes through the object . then there will be a loss .if (current or voltage) the electrical energy is converted into light source , mechanical energy( rotation of fan),chemical reaction(electroplating) as heat (iron box ). so when no object(load) is connected to the plug point there wont be any loss if you r switch on the switch too.
What type of energy transformation is it when the electric toaster is plugged into the outlet and is used to to make dinner?
Electrical energy is converted into heat energy in this case.
Is it a fire hazard when the wall outlet that has an electric heater plugged into it is hot?
Yes and Very Possible! Bad connections cause heat so the outlet may be defectice. The outlet or the supply line may also not be rated to supply the current (amperage) required by the heater.

Can you glue the cap to the water outlet back on in a 99 Dodge Intrepid 2.7?
no. the heat and pressure will blow it off. you will need to get the petcock repaired or plugged, probably pretty cheap repair at a rad shop. Replace the water outlet, they fail all the time.
Is a television converting electrical energy to light energy?
Yes it is. And don't forget about the sound energy and heat energy that also come out of a TV receiver. Those are also products converted from the electrical energy that the set gets from the wall outlet.
What energy transformations in a tv?
A television receiver uses electrical energy, either from batteries or from the electrical outlet it's plugged into, and converts that energy into a tiny bit of light energy, a moderate amount of sound energy, and a considerable amount of heat energy.
What type of heat sink or cooler attached to the motherboard?
plugged into motherboard
If heater core is plugged would there be any heat?
Usually, with a plugged heater core there will be a bit of heat but not very much..I've only seen a few so plugged that there was no heat. One way to tell is to (carefully) touch the heater hoses just where they go into the heater core. Both hoses should be about the same temperature. If not and the heater control valve is open - then the heater core being plugged is a very good possibility.

How can I hook up my natural gas central heat to my generator?
I did this last year for about 6 days and it worked wonderfully. Most gas central heater are 110 and the easy way (wich is what I did) was to locate my furnace. It was plugged into an outlet just like any other appliance. I simply plugged it into a medium duty extension cord and plugged the cord into the generator. The generator was a 3500watt and ran my CH&A, TV, Surround Sound, lights and 2 refrigerators. We also cooked on a George Forman. Hope this helps.

How does an electric kettle get energy?
The kettle has to be plugged in to an energy supply before it can heat up.
