- Fact 2 - Electricity is also
referred to as an energy carrier. We get electricity from the
conversion of other sources of energy, such as coal, nuclear, or
solar energy
- Fact 3 - An electron is an
elementary particle with a negative charge. A Proton is an
elementary particle with a positive charge
- Fact 4 - An electric charge
originates in the atom, in which its most familiar carriers are
the electron and proton
- Fact 5 - An electric charge may be
transferred either by direct contact or by passing along a
conducting material, such as a wire
- Fact 6 - Electric current is
measured in amperes, and is defined as the rate at which
electric charge travels through a conductor
- Fact 7 - Static electricity and
electric current are two separate phenomena, both involving
electric charge, and may occur simultaneously in the same object
- Fact 8 - force that causes the
electrons to move in an electrical circuit is called the
electromotive force, or EMF
- Fact 9 - There are many sources of
EMF, the most common being batteries and electrical generators.
- Fact 10 - The word 'electricity' is
derived from 'electron', the Greek word for amber, a yellow
transparent substance, remarkable for its electrical power when
rubbed
- Fact 11 - Electricity itself is
neither renewable or non-renewable but the energy sources we use
to make electricity can be renewable or non-renewable
- Fact 12 -
- Fact 13 - Benjamin Franklin
demonstrated that lightning is electricity. He tied a key to a
kite string during a thunderstorm, and proved that static
electricity and lightning were the same thing.
- Fact 14 - In 1879 Thomas Edison
invented the first long-lasting incandescent light bulb that
could be used for about 40 hours without burning out. By 1880,
his bulbs could be used for 1,200 hours.
- Fact 15 - In 1826 Georg Ohm defined
the relationship between power, voltage, current and resistance
in Ohms Law
- Fact 15 - In 1844 Samuel Morse
invented the electric telegraph, a machine that could send
messages long distances across wires - see
Facts about the Morse Code
- Fact 15 - In 1888 Charles Brush
used a large windmill to generate electricity in order to charge
batteries in the cellar of his home in Cleveland, Ohio.
- Fact 15 - J. Spangler invented the
first electric vacuum cleaner in 1911
- Fact 15 - A. Goss invented the
electric refrigerator in 1913
- Fact 15 - The world' s first
nuclear power plant in Russia started generating
electricity in 1954.
- Fact 15 - Electricity became
available over 100 years ago - The ability to harness energy and
produce electricity has changed the
World.
