why is my toaster hot but my fridge cold yet they both run on electricity?

Answer 1

they are made to run like that.. thats why..

Answer 2

You've heard of Alternating current? Well, one way it is hot, the other way it is cold.
It all depends which way the electricity goes through it!
:-)
OK. No one has explained the fridge for you.
Get a bicycle pump, put a thumb over the end, and press it down.
The pump gets hot right?
That is because, when a gas is compressed it gets hot.
Now feel the temperature of the liquid that comes out of a spray can. It is cold right? That is because when a gas under pressure expands, it gets cool.
That is how a fridge works.
Your fridge has a tube filled with a special type of liquid called refrigerant. half of the tube is outside the back of the fridge, and the other half is inside it There is an electric pump, that compresses the gas into a liquid, thus making it hot, behind the fridge.
Where the tube enters the fridge, there is a very tiny restriction, so the compressed liquid sprays through it like the nozzle of a spray can, so the gas gets very cold. the cold gas is in the tubes inside the fridge, so inside it gets cold.
Does that help?

Answer 3

Your fridge does get hot, both from the electrical current it uses and from taking the heat energy out of the interior. The difference is the fridge uses a refrigerant that absorbs the heat energy from the inside and transfers it to the coils on the outside of the unit, making the inside cold.

Answer 4

When the electrical current passes through the filaments in the toaster, they get hot due to the resistance in the wire.

By comparison your refrigerator uses the electrical current to power the compressor motor. This circulates a coolant through the system and transfers heat from inside the fridge to the air outside of it.

Sort of like asking why electricity produces light from a light bulb but music from a radio.

Answer 5

Your fridge IS hot. Reach around the back, feel the heat. A fridge puts out more heat from the back than there is cold in the inside.
Eelctricity in a fridge is used to drive a gas based heat exchanger system that takes low temperature heat from the inside and dump it as higher temperature heat on the outside (through the fins and piping in the back)

Answer 6

Because your toaster uses electricity to heat coils to cook your bread. And your fridge uses electricity to run freon through it to draw away the heat from inside, creating cold.

You will notice that parts of your fridge are warm, but they are not inside the storage area...they are behind the fridge and under it.

Answer 7

This is what makes electricity so versatile. In one case, the current is run through thin strips of metal that get red hot and toasts your English muffins - in the other case, it is used to run a motor that compresses a gas that evaporates at a very low temperature and is very good at removing the heat from that jar of jelly in the refridgerator to put on those English muffins.

Answer 8

Both are run by a complex circuit and machinery....
Both complex circuits and machineries are powered by electricity....
However, each of them does a different work. just like a light bulb is powered by electricity but does neither cool or heat your food... its circuit is designed to produce only light (and its quite hot because all energy transformation requires heat to be released. that's why the back of your fridge is hot, try it...)

Answer 9

your toaster is hot because it works by resistence.

when curent is passed threw a small wire, it makes

the wire heat up . if you look into the top you can see this.

it is this resistence that makes your toast cook,

Answer 10

The different machines transfer the energy

Answer 11

different electricl currence runing though them there may be more in ur toaster than ur fidge say but ur fridge if filled with very dangers chemicas so that it stays cold
