Electric Currents

In order for electricity to be useful, we need...

• A steady flow electricity.

• An overflow of protons.

• A light bulb that never runs out.

True or False: An electric current can happen all on it's own

• True

• False

A conductor is any material that

• can be measured

• allows electrons to move through it easily

• resists the motion of electrons

How does a SWITCH work?

• The switch increases the amount of electrons flowing in the wires.

• The switch makes the electrons in a wire move faster.

• The switch opens or closes the circuit.

For electric current to flow, do you need a closed or open circuit?

• Closed.

• Open.

A circuit is...

• A way of routing electricity along a path

• When you measure how much an item weighs

When electrons move from one place to another you get...

• a solid to a liquid

• electricity

• evaporation

What is the function of a power source in circuit?

• To cause motion of protons.

• To generate a steady supply of electrons.

• To deflect any static electricity.

Insulators are a material that electrons have a hard time flowing through

• True

• False

What is a LOAD in a circuit?

• A device that uses magnetism.

• A device that uses electricity.

• A device that uses solar energy.
