Identify what each component in the circuit does.

coil wire

• Provides the pathway to carry electricity into the core

• Provides the pathway to carry electricity from component to component.

Identify what each component does in the circuit

switch

• Controls the flow of electricity by only closing the circuit

• Controls the flow of electricity by only opening the circuit

• Controls the flow of electricity by opening and closing the circuit.

A student set a compass on top of a wire not yet connected in a circuit. When she connected the wire to the positive side of the D-cell, the compass needle moved. Why would a compass needle change position when the  circuit was closed?

• A magnetic field surrounds a wire when electric current flows through it.

• A force field surrounds a wire when electric current flows around it.

• A magnetic field surrounds a wire when electric current flows around it.

• A force field surrounds a wire when electric current flows through it.
