👉 Originally, a property of amber and certain other nonconducting substances to attract lightweight material when rubbed, or the cause of this property; now understood to be a phenomenon caused by the distribution and movement of charged subatomic particles and their interaction with the electromagnetic field.
Alright class, settle down, let’s dive in today!
We're talking about
electricity
, a really important thing – it powers our lives, you see!
Now, that dictionary definition is quite a mouthful, isn’t it? Let's break it down piece by piece, like building with blocks.
First, we have the old story of
amber and stone
. Remember rubbing amber on wool? It would suddenly grab bits of dust and fluff – a magical trick! That was its
original
way to be known. It’s like a little surprise, you see it shown!
Then, as scientists got clever and learned more about how things work, they realized it wasn't just magic at all. It’s not just a property of amber, standing tall.
Instead, electricity is
caused
by something much smaller -
charged subatomic particles
– tiny bits within everything! These little guys have a charge, you see, positive or negative, wild and free!
And these charged particles move around, they don't just sit still, it’s true. They dance with the
electromagnetic field
, working as a team for me and you! This field is all around us, a powerful, unseen grace, influencing everything in this very place!
So, to put it simply: Electricity is when tiny charged particles move and play, creating a force that brightens up our day.
Do you have any questions about this fascinating phenomenon? Don’t be shy, let's discuss and see if you can apply what we've learned.
