Electrical Circuits

Learn about electrical circuits! Match vocab, identify circuit types, and classify conductors/insulators.

Vocabulary Matching Match the vocabulary term to the correct definition. Circuit the path in which an electrical current passes Energy Source provides the power to the circuit (ex: battery) Complete Circuit a circuit with no breaks or gaps in the path Incomplete Circuit a circuit with a break or gap in the path Switch used to open or close a circuit Conductor allows for the easy passage of electricity or heat Insulator resists the passage of electricity or heat 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 The paper clip is used instead of a switch in this example to close the circuit. What physical property of a paper clip makes its use a good plan? It is an insulator It is soluble It is a conductor It is magnetic 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 When electricity travels through wires, it always produces - heat or thermal energy nuclear energy mechanical energy light energy Label the parts of a circuit:energy sourceloadswitchconductor energy source load conductor switch Classify the objects by its conductivity.
