Negatively charged atoms

Positively charged subatomic particles

Neutrally-charged subatomic particles

Negatively charged subatomic particles

A short burst of electricity.

A steady flow of electricity.

Rubber is a good conductor, most metals are good insulators.

Rubber is a good insulator; most metals are good conductors.

Rubber conducts electrons; most metals conduct protons.

Rubber is a good power source; most metals are good conductors.

The power source would no longer provide a flow of electrons.

Current electricity would become static electricity.

The circuit would be broken.

We'd be in danger of harm from electric shocks.

A switch

A current

A load

A power source

The current reverses direction

Nothing happens

The electrons shoot out from the negative terminal

The electrons stop flowing, and the current stops

An electric current can supply electrons to a circuit

An electric circuit carries electrons to a current

An electric current is the flow of electrons through a circuit

A circuit is the flow of electrons through an electric current

Because electrons flow too quickly

Because energy is released all at once

Because it cannot supply enough electrons

Because it only occurs in lightning

By providing it with electrons

By closing the circuit

By opening the circuit

By providing it with insulation

Lengthening the wire

Adding a second load

Closing the circuit

Opening the circuit
