Electric Modern Lives

Electricity at a glimpse

• Electricity all depends on charges. • Protons are positive, electrons are negative.• Opposites attract• Conductors- good for electrons to move

through• Insulators- bad for electrons to move through• Powers many things in the world

Electricity- Secondary Energy Source

Because other energy sources are used to create electricity it is a secondary energy source. The process of converting the energy from coal, natural gas and other primary sources gives you electricity.

Think of electricity as a by-product of the natural resources in our world.

Lightning

• Lightning is a static discharge. • http://green.nationalgeographic.com/environ

ment/natural-disasters/lightning-profile.html• This site gives vital information on lightning

and its amazing power. Not to mention you get to knock someone over.

Lightning cont.

• There are two kinds of lightning.• Positive and negative lightning.• Positive lightning happens only 1 out of 20

thunderheads contain enough protons to create such a strike.

• The most common kind of lightning is negative.

Electricity and its equivalents

• Electricity is easily converted into any other type of energy. If a light bulb is given electrical power, it changes it to light energy and thermal energy. A ceiling fan converts this power into mechanical energy.

Where does this all come from?

• Electrical power can come from anything because it is just the rate at which electrical energy is changed. Electric energy can come from a battery, or through a larger producer like the power company.
