Electric Current and Simple Circuits

Atoms are made of what?

A proton has what type of charge?

A(n) electron has what type of charge?

When will an atom become electrically neutral?

When an object gains electrons, what type of charge is that called?

When an object loses electrons, what type of charge is that called?

When two charged objects have the same type of charge, what will happen to the object?

If the distance between two charged objects stays constant and close to one another, what will happen to its electric force?

If electrons cannot easily move through a material, what type of material is it using?

Electrons can transfer between objects by contact, induction, or conduction.

An electric discharge is the gain of an unbalanced electric charge

Movement of electrically charged particles going in the same direction produces what?

A closed, or complete path in which an electric current travels is called what?

As electrons move from atom to atom, their kinetic energy transforms to other useful energy forms, such as light and thermal energy.

Electrons continually added to one end of a wire create a constant one-way flow of electrons known as alternating current.

An electric current that continually reverses direction is known as an alternating current.

The flow of electric charges of an alternating current changes direction many times per second.

Electric current is a measure of how difficult it is for an electric current to flow in a material.

A resistor is used to limit the electric current flow within the circuit.

A good conductor has more electric resistance.

The voltage of an electric circuit is the amount of energy used to move one coulomb of electrons through the circuit.

The voltage measured across a part of a circuit tells you how much current is going through that part of the circuit.
