Enjoy a wide range of fun electricity facts for kids. Electricity
plays an important role in everyday life, learn more about static electricity,
electric eels, circuits, lightning, electric shock, volts, amps and much more.
society relies heavily on the convenience and versatility of electricity.
It powers your microwave, helps light your house, lets you watch TV and so
current is measured in amperes (amps).
potential energy is measured in volts.
positive charges repel each other, as do two negative charges. Opposite
charges on the other hand attract each other.
an electric charge builds up on the surface of an object it creates static
electricity. You have probably experienced static electricity in the form
of a small electric shock, which is what happens when the electric charge
is quickly neutralized by an opposite charge.
eels can produce strong electric shocks of around 500 volts for both self-defense
circuits can contain parts such as switches, transformers, resistors and
common way to produce electricity is by hydropower, a process that
generates electricity by using water to spin turbines attached to
world’s biggest source of energy for producing electricity comes
from coal. The burning of coal in furnaces heats boiler water until it
becomes steam which then spins turbines attached to generators.
is a discharge of electricity in the atmosphere. Lightning bolts can
travel at around 210,000 kph (130,000 mph), while reaching
nearly 30,000 °C (54,000 °F) in temperature.
plays a role in the way your heart beats. Muscle cells in the
heart are contracted by electricity going through the heart.
Electrocardiogram (ECG) machines used in hospitals measure the electricity
going through someone’s heart, when the person is healthy it usually shows
a line moving across a screen with regular spikes as the heart beats.
may have heard of direct current (DC) and alternating current (AC). The
difference between the two is in the way the electrons flow. In DC
electrons move in a single direction while in AC they change directions,
switching between backwards and forwards. The electricity use in your home
is AC while DC comes from sources that include batteries.
in the 1880’s there was even a ‘war of currents’ between Thomas Edison
(who helped invent DC) and Nikola Tesla (who helped invent AC). Both
wanted their system to be used with AC eventually winning out due to the
fact that it is safer and can be used over longer distances.
fields work in a similar way to gravity with an important exception being
that while gravity always attracts, electric fields can either attract or
Benjamin Franklin carried out extensive electricity research in the 18th
century, inventing the lightning rod amongst his many discoveries.
Lightning rods protect buildings in the event of lightning by conducting
lightning strikes through a grounded wire.
