ElectricityWhen Charges Align

Each part has two opposite charges.

Like charges repel each other.

Unlike charges attract each other.

ElectricityWhen the parts are aligned,

the flow goes in both directions.

What flows?

The charge.

What else flows like a charge?

Laughter is often called “infectious”—when you hear another person laugh, you sometimes start to laugh too,even if you don’t really know what the other person is laughing about.

The laughter seems to travel from person to person—but it is not really the laughter that’s moving (you are not laughing your neighbor’s laugh), it is just that the person who hears a neighbor laugh

also starts to laugh.

The person’s mood (energy) has changed, but nothing has changed in the person’s body (matter).

Electrical charges can flow through objects

…and from object to object.

The movement of electric charges from one point to another is electrical current.

from one end to the other…
