• C is greater than V

• C is less than V

• C is equal to V

• C is zero

What is a Short Circuit?

• A path with high resistance.

• An incomplete circuit through which electricity will not flow.

• A circuit that allows current to take the path of least resistance.

• A rapid and interrupted current.

What is an Open Circuit?

(Re-think your answer before continuing.)

• A path with high resistance.

• An incomplete circuit through which electricity will not flow.

• A path with low resistance.

• An electric circuit with a single path.

If a Series Circuit is an electric circuit with a single path...

Then a Parallel Circuit is...

(Re-think your answer before continuing.)

• A circuit with a path of low resistance.

• A complete circuit.

• A circuit consisting of parallel connections.

• A circuit that contains more than one path for current flow.

The total resistance in this circuit is...

• 350 Ohms

• 400 Ohms

• 450 Ohms

• 500 Ohms
