10
Q

Which particles typically flow in a circuit?

(Electrons, protons, or neutrons)

A

Electrons

(they are on the outside edges of the atoms, and can jump from atom to atom if they are not held too tightly by the nucleus.)

A

Protons

Neutrons

Electrons

14
Q

Electricity

Conductor

A

A material in which electrons are able to move easily.

15
Q

Electricity

Charging by induction

A

The rearrangement of electrons on a neutral object caused by a nearby charged object

16
Q

A material in which the nucleus only loosely holds onto the electrons on the surface of the atom.

A

Conductor.

17
Q

A method of charging an object where you scare the electons away, leaving a positive area behind.

A

Charging by Induction

18
Q

Electricity

Electric current

A

The net movement of electric charges in a single direction
