The definition of electricity is the flow of charge . Usually our charges will be carried by free-flowing electrons. Negatively-charged electrons are loosely held to atoms of conductive materials. With a little push we can free electrons from atoms and get them to flow in a generally uniform direction.
How do you explain electric current to a child?
Current is the flow of an electric charge . Current flows through a circuit when a voltage is placed across two points of a conductor. ... Flow of Electrons. In an electronic circuit, the current is the flow of electrons.

What is electricity simple words?
Electricity is the presence and flow of electric charge. Using electricity we can transfer energy in ways that allow us to do simple chores. Its best-known form is the flow of electrons through conductors such as copper wires. The word “electricity” is sometimes used to mean “ electrical energy “.
What are the 4 types of electricity?
- Static Electricity. Static Electricity is nothing but the contact between equal amount of protons and electrons (positively and negatively charged subatomic particles). ...
- Current Electricity. Current Electricity is a flow of electric charge across an electrical field. ...
- Hydro Electricity. ...
- Solar Electricity.
Why is it called electricity?
The Greeks first discovered electricity about 3000 years ago. Its name came from the word “elektron”, which means amber. ... When the key became charged with electricity he had proof that lightning flowed like water. Mr Franklin’s experiments led to his invention of the lightning rod.
What are the two types of electricity?
Current electricity is a constant flow of electrons. There are two kinds of current electricity: direct current (DC) and alternating current (AC) .
How do you introduce electricity?
Electricity is a form of energy involving the flow of electrons . All matter is made up of atoms, which has a center called a nucleus. The nucleus contains positively charged particles called protons and uncharged particles called neutrons.
Where is electricity most used?
China consumes the most electricity of any country in the world. The United States ranks as the second-largest electricity consumer, at 4,194 terawatt hours in 2019 and was followed by India at a significant margin.
Is electricity a need or want?
Electricity is one of those tricky subjects to tackle, because it is kind of in a limbo state, not really a need but not quite a want . Bare facts- humanity has survived thousands of years without electricity and in large parts of the world today still manages fine without.
What is electricity kid friendly definition?
Electricity is a type of energy that can build up in one place or flow from one place to another . When electricity gathers in one place it is known as static electricity (the word static means something that does not move); electricity that moves from one place to another is called current electricity.
Where is electricity found?
Electricity is not only found in power lines and electronics made by man , but is also found in nature. In fact electricity is all around us. We see it in lightning storms, animals use it as a defense, even our bodies use it to send messages to our muscles.
Where is the origin of electricity?
This word comes from the Greek word elektron which means amber . Earlier, electricity generation began over 100 years ago, houses were lit with kerosene lamps, food was chilled in iceboxes, and rooms were warmed by wood-burning or coal-burning stoves.
How do you explain electricity to a 7 year old?
