Electric Circuits

Electric current

• Material that allows electric current to flow through easily

• The flow of electricity around a circuit

• To move or travel smoothly in a certain direction

• The pathway through which electrical current flows

Flow

• The flow of electricity around a circuit

• Material that stops current from flowing

• The pathway through which electrical current flows

• To move or travel smoothly in a certain direction

Insulator

• Material that allows electric current to flow through easily

Material that allows electric current to flow through easily

• Electric current

• Conductor

• Insulator

• Electric circuit

A closed path through which an electrical current travels is called—

• energy.

• a conductor.

• a circuit.

• an insulator.

A student collected a switch, wires, and light bulb. If the student wants to make a complete circuit, what does she still need to collect?

• battery

• paper clip

• electrical cord

• wooden stick
