Using electricity safely

The batteriesA battery is two or more electric cells joined together that can produce an electric current when connected to an electric circuit. we use for torches and radios are mostly 1.5 volts or 9 volts while the mains electricityElectric current supplied to our homes from the national grid. in our homes is 230 volts. The higher the voltageA measure of the energy of the electric charges in a circuit. in a circuit, the greater the electric currentElectric current is a flow of electric charges (electrons). can be. The low voltages provided by batteries means they are perfectly safe, but mains electricity can kill if we don't respect it.

Stay safe

Never poke your fingers or anything else into electric sockets, toasters or any other electrical appliance.
Never touch electric appliances with wet hands.
Never use electric appliances near water.
Never pull a plug out of a socket by pulling on the electricity flexElectric wire covered in an insulating material like plastic.. Hold the plug instead.
Never carry an electrical appliance by its electricity flex.
Never use an electrical appliance if it has a broken electricity flex.

Fossil fuels won't go on for ever - oil could run out in 30 years.
Michael Faraday (1791-1867) is one of the most famous people involved in the discovery and harnessing of electromagnetic force.
At Deptford in 1891, electrical engineer Sebastian Ziani de Ferranti (1864-1930) designed and built the first power station and supply network. His basic system is still used around the world.
Fossil fuels won't go on for ever - coal could run out in 250 years.
Electric shock victims often can't let go of the thing that is passing the electric current into their body. That's because the electricity makes their muscles contract.
Save energy - Boil just enough water for the number of hot drinks you want to make - that way you won't waste energy.
Michael Faraday (1791-1867) was the first person to create a way of generating a constant current of electricity. His invention led to the power stations we know today.
Thomas Alva Edison 1847-1931 is one of the most successful inventors ever, applying for over 1,300 patents by 1910, mainly to do with electrical or mechanical development.
The Italian inventor Alessandro Volta (1745-1827) is best known for his work on electric current.
What is a watt? Why is it called a watt? It's a unit measuring electric power, named after James Watt (1736-1819).
High voltage electricity is carried across the country by pylons and 'stepped down' for domestic use at substations. The National Grid supplies electricity all over the country.
Benjamin Franklin (1706-1790) developed the first lightning conductor after flying a kite in a thunderstorm. A spectacular but very dangerous experiment!
Electricity used at home is metered in 'units' or kilowatt hours (kWh). Each unit is the same as 1,000 watts of electricity used for 1 hour. 1 unit = 1kWh.
All electrical appliances are rated in watts (W) or kilowatts (kW) ( One kilowatt is the same as 1,000 watts). You can use the ratings to compare how much electricity they use.
The ampere is named after André-Marie Ampère (1775-1836). He discovered many of the mathematical principles of electromagnetism.
The first turbine engines were designed by Charles Parson (1854-1931). Today turbine engines used to generate electricity are still based on his designs.
Save energy - Finished playing on your games console or other equipment? Remember to switch off!
In 1771 Luigi Galvani used electricity to make a dead frog's leg jump!
Save energy - Make sure the dishwasher and washing machine are full before you turn them on and use the lower temperature settings.
In August 1887 the London Electric Supply Corporation commissioned Ferranti to build the first power station. Today our electricity supply is still based on the system that Ferranti designed.
In 1800 Alessandro Volta built the world's first battery from discs of copper and zinc sandwiched between cardboard moistened with a salty water.
An electric eel can produce powerful electric shocks: up to 500 volts and one ampere of current (in other words, 500 watts).
Fossil fuels won't go on for ever - gas could run out in 40 years.
In 1831 Michael Faraday demonstrated electromagnetic force at the the Royal Institution in London, a famous centre for scientific education and research.
In 15 minutes, the sun radiates as much energy onto Earth as all the people on the planet during an entire year. Just imagine if we could channel the sun's energy effectively!
What is a volt? And why is it called a volt? The volt measures electromotive force. It was named after the Italian inventor Alessandro Volta (1745-1827)
Modern power stations and steam turbines use the same engineering principles that James Watt (1736-1819) applied when he invented the steam engine.
Save energy - Use energy efficient light bulbs and, when you are leaving a room empty, remember to turn the lights off.
Today we still use words that Benjamin Franklin (1706-1790) introduced: battery, conductor, positive and negative charge, electric shock and electrician.
Save energy - Don't forget to switch your TV and computer off when you have finished using them.
In the 1780s, Alessandro Volta invented the first battery - all because of Luigi Galvani's experiments with dead frogs.
