Which of the following best describes a conductor?

• A material that opposes the passage of an electric current

• A material that does not transfer an electric current

• A material that transfers an electric current

• A material that is in between a conductor and an insulator

What is resistance in the context of electricity?

• The potential difference in charge between two points

• The uniform flow of electrons through a circuit

• The degree to which an object opposes the passage of an electric current

• The transfer of electrons that results in a static charge

What is the relationship between voltage, resistance, and current as per the document?

• Voltage is the flow of electricity, and resistance is the potential difference in charge

• Current is the potential difference in charge, and voltage is the flow of electricity

• Resistance determines the flow of electricity, and voltage is the potential difference in charge

• Voltage is the potential difference in charge, and current is the uniform flow of electrons

Which of the following is NOT a basic principle applicable to circuits?

• Electrons need a complete, conducting pathway (circuit)

• Electrons move around the circuit, traveling from high to low potential

• Thermal energy is transferred to the surroundings

• Electronic circuits can only be composed of capacitors and resistors

What is the role of transistors in electronic circuits?

• To transfer energy to perform some useful function

• To conduct investigations and evaluate experimental designs

• To amplify electrical signals or act like a light switch, turning the flow of electricity on or off

• To compare generators and motors and how they function

What can be inferred about electric and magnetic (electromagnetic) forces?

• They can only be attractive in nature

• They are not dependent on the magnitudes of the charges, currents, or magnetic strengths involved

• They can be both attractive or repulsive and depend on the magnitudes of the charges, currents, or magnetic strengths involved

• They cannot be mapped or have any effect on a test object
