How Does Electricity Work? | ELECTRICITY Science


everyone please welcome my next guest
generic electron now mister electron nice to have you on the show. don’t you find it at
least a little ionic that you’re so negative but you love to be around
positive molecules hey squints, princess photosynthesis
asks can you explain electricity and is it related to heat? electricity and heat
are kind of connected like in light bulbs how they get hot when electricity
is going through them but electrons are at the heart of electricity shocking
right? remember every atom has little electrons flying around it they’re
negatively charged so they are attracted to positive charges. electricity is all
about taking advantage of this attraction of negative electrons to
plus charges. take a look at a battery for example a simple source of
electricity. one side is the minus end the other is the plus end. inside the
battery there is a barrier that separates the two ends. the minus end is
full of extra electrons that are itching to leave and the plus end has atoms and
molecules hankering for extra electrons. thanks to the barrier the only way those
electrons can fulfill their dream of frolicking with positive molecules is to
go through some material that will pass those electrons on like the world’s
smallest game of hot potato. some materials are good insulators meaning
when extra electrons hit it the molecules soaked them up instead of
passing them on. this is bad for passing an electric current like someone pulling
out sour cream and eating that hot potato. It’s not a baked potato!
that’s why wires are covered with rubber or plastic which are good insulators to
keep the electricity from flowing into your hands. the inside of wires is made
from metal usually copper which is a good conductor. metal atoms are a great
choice because they already have extra electrons flying around them so they
will quickly pass any additional ones that come their way.
electrons fly through metal wires towards that positive end at incredibly
high speeds which means these electrons carry a lot of energy. now if our whole
goal in life was to make electrons happy we would just connect the minus end to
the plus end and let them find their mate. but we as humans are selfish so we
make those electrons work for us as they travel around. we can stick an
object that needs energy to work called the load in the middle of the wire like
a light bulb for example. in old light bulbs electrons zip through the
wiring bumping into large metal atoms in the bulb on their way. all this
bumping heats up the atoms so much that the atoms reach temperatures of 4000
degrees Fahrenheit like metal in a fire these heated atoms glow sending photons
of light flying and lighting up the room. so no matter the load
whenever electricity is flowing remember to thank those hard-working negative
particles (thank you) who volunteered their time so I can play pokemon so I
can do work on my phone. stay electric keep asking questions and keep on
squinting. interesting… it’s not on but do you have a question that you’d like to
