How can electricity power so many things?

Answer 1

There are umpteen things, that use electricity, electric fish, humans conduct or produce it from potassium and sodium in the cells.Stones,like amber create it when rubbed on cloth.Pierre Currie, studied piezzo quartz etc.Lighting in the sky,is caused by different pressures and conducted through, nitrogen in the air.

Answer 2

Electricity provides energy. Different devices use the energy in different ways.

Some space heaters use the el. energy to make heat. Electron flow thru some substances causes a sort of internal friction with the electrons in that substance and produces heat.

An incandescent light bulb does a similar thing but produces so much friction that it produces both heat and light. About 85% of the energy goes to heat only about 15% of the energy goes to light.

Forescent lights work similarly, but the electrons are moving thru a gas like neon. Less energy is used in heat, more makes light.

Electric motors use the energy to make magnetism and repel other magnets (permanent or electromagnets) and produce motion.

Computers use the el. energy to store and process information. Many microswitces in the computer are either 'on' or 'off' because of a small electrical charge in them. The information is usually stored on a hard drive in magnetic form, accessed by the computer using a program to interpret the information etc....

Refrigerators/air conditioners use the electricity in motors to turn a pump (compressor) which puts a gas under pressure causing the temp. to rise, the excess heat dissipates thru coils until the gas condenses (hence the condenser) the condensed gas is allowed to go thru a valve to lower its pressure an it 'boils' and takes heat from the inside of the refrigerator. Then the cycle repeats.

Answer 3

computer

tv

light

oven

rice cooker

etc.....

Actually, everything uses electricity, from our bodies and their nervous system, all the way to every (covalent) chemical reaction in the universe, because the transfer and accumulation of electrons constitutes electricity

Answer 4

We use electricity constantly in our daily lives. It is one of the most important types of power and energy that we use.

Electricity in our House

Electricity travels to our house over power lines from a big power plant somewhere far away. Your parents actually have to pay for how much electricity is used. There is an electric meter outside of your house that keeps track of this. The more the lights are on or the TV is running, the higher the bill will be from the electric company.

Once the power comes to our house, it gets sent out on wires to sockets in the walls. We can plug all sorts of things into these sockets and use the power from electricity. In our homes we power lights, air conditioning, televisions, ovens, and more from electricity. Without it, we'd be bored, hot, and sitting in the dark.

Batteries

Some electricity comes from batteries. Batteries use chemicals to store up electricity that can power devices like cell phones, radio controlled cars, handheld Video Games, and flashlights. Batteries run out of power after a while and either need to be recharged or recycled. Remember to always recycle your batteries as there are dangerous chemicals in them!

Other uses

Electricity is used in cars too. There is a big battery to help the engine get started. Then the engine generates electricity for the radio, lights, and other cool features. Some cars run 100% on electricity by using big batteries that get charged up from a wall socket.

Electricity also can make magnetism. This can be used to create giant powerful magnets as well as fast and quiet magnetic trains. Electric motors generate magnetism to turn the motor and cause movement for all sorts of uses.

History

One of the first great uses of electricity was for communication using Morse Code and the Telegraph in 1840. This allowed messages to be sent long distances in an instant. After that came the telephone and the radio and, in 1880, electric light. These inventions and the use of electricity changed the world. Electricity continued to change the world with new inventions such as the TV and, even more recently, the personal computer and the cell phone.

Fun facts about the Uses of Electricity

• 25% of the city of San Francisco's energy is generated by wind power.
• Electric eels use electricity to ward off enemies. They can produce a shock of around 500 volts.
• Our bodies use electricity to communicate including telling our heart to keep beating.
• Two famous scientists, Thomas Edison and Nikola Tesla, once had an argument over what kind of electricity we should use in our homes, AC or DC. Tesla won and AC is delivered to most homes still today.
• Electricity was first used in homes for lighting.

Answer 5

Electricity can power many things because it is a versatile form of energy that can be easily generated, transmitted, and transformed into other forms of energy such as light, heat, and motion. By connecting electrical devices to a power source, such as a battery or a power grid, electricity can flow through circuits and provide the energy needed to operate various electronic devices and appliances.

Answer 6

it is what allows us to use electronic devices which is needed for basically everything in the world.

Answer 7

The Universe is Electric, E=mc^2 is electricity. Try to name something that is not electricity.
