Wakaba:
Ciao, everyone! Wakaba here. How are you all doing?
I’m doing great too.
I’ve decided to join the “Dig Here, Bowwow!!”!

Morio:
Whoa, that came out of nowhere.

Wakaba:
Well, I heard you’re going to start New Series about
“Machine and Electricity.”

To be honest, electricity is full of things I don’t really understand.

Morio:
Yeah, I felt the same way.

In the world of Machine — including spring machines —
electricity is used everywhere.

Motors, servo systems, sensors, control panels…
there’s electricity involved in almost everything.

But actually—

If someone asks,
“What exactly is electricity?”

it’s surprisingly hard to explain.

So in this series,
we’ll start from the very basics of electricity
and gradually dig deeper, all the way to
electrical control in Machine.

Wakaba:
Alright then, let me ask right away.

What is electricity in the first place?

Morio:
To put it simply,
Electricity is the movement of electrons.

Wakaba:
Electrons?

Morio:
Right.

Electrons are extremely tiny particles
inside atoms, which make up all matter.

Inside an atom, there are:

Protons (positive charge)
Electrons (negative charge)

Electrons move around the nucleus,
and inside metals, they can move relatively freely.

Wakaba:
Protons and electrons…
I think I learned that a long time ago in school.

Morio:
When those electrons move—
that’s electricity.

Wakaba:
Hmm… this is starting to sound complicated.
So electricity is actually tiny particles moving?

Morio:
Exactly.

Inside an electric wire,
an enormous number of electrons are moving.

To make this easier to imagine,
let’s compare it to water flow.

Think about a water pipe.

– Pipe → Electric wire
– Water → Electrons
– Water flow → Electric current

Just like water flows through a pipe,
electrons move through a wire.

Wakaba:
Ah, I see.

So electricity flows like water.

Morio:
That’s a helpful way to picture it.

And by using that flow of electrons,
we can make many things happen.

For example, in Machine, we use electricity to:

– Rotate motors
– Heat heaters
– Light lamps
– Control positions with servo systems

All of these work
because the motion of electrons becomes energy.

Wakaba:
Wow, electrons are really hard workers.

Morio:
They really are.
And there are an unbelievable number of electrons inside a wire.

Wakaba:
How manyt?

Morio:
In just 1 inch of wire,
there can be trillions of electrons.

Wakaba:
Seriously?!

That’s impossible to imagine…

But if there are that many hard workers,
I guess labor shortages wouldn’t be a problem!

🐾 Key Points

– Electricity is the movement of electrons

– Inside wires, electrons are constantly flowing

– That energy is used to operate Machine

Wakaba:
But wait.

I understand that electrons move, but…

What exactly is Electric Current?

Back in school, they said
current flows from plus to minus,
but electrons move from minus to plus.

That’s where I started getting confused.

Morio:
Good catch.
That’s a great question.
And that will be the topic of the next episode.
