Vocabulary Matching Match the vocabulary term to the correct definition. Energy Source provides the power to the circuit (ex: battery) Closed (complete) Circuit a circuit with no breaks or gaps in the path Open (incomplete) Circuit a circuit with a break or gap in the path Switch used to open or close a circuit Conductor Something that allows electricity to flow Insulator Something that does not allow electricity to flow What type of circuit is this? Closed Circuit Open Circuit An Incomplete Circuit Parallel What would happen to this circuit if the switch was opened instead of closed? The bulb will light The bulb will not light The bulb will be dimmer If a cut is made at the point shown, how many bulbs will light up? 0 1 2 3 Why will the bulb not light up in this scenario The switch needs to be open The battery is dead Yarn is not a conductor of electricity The circuit needs an additional battery Which part of this circuit will not work and why? the battery because it is not connected correctly the bell because it is not connected correctly the light bulb because it is not connected correctly Classify the objects by their conductivity.
