Electric Resistance and Current Question

What is an electric circuit?

• A path for electric current to flow

• A device that stores energy

• A type of battery

• A form of insulation

What three things does every circuit typically contain?

• Resistor, capacitor, inductor

• Source, path, load

• Battery, switch, light bulb

• Wire, magnet, motor

What is electric current?

• The flow of electric charge

• The resistance to electric flow

• The storage of electric energy

• The conversion of electric energy

What happens if the wire in a circuit is not connected to both terminals of the battery?

• The circuit will overheat

• The circuit will not work

• The circuit will short circuit

• The circuit will increase resistance

What is the symbol for current and what unit is used to measure current?

• I, Ampere

• V, Volt

• R, Ohm

• P, Watt

What is resistance?

• The ability to conduct electricity

• The opposition to the flow of electric current

• The storage of electric charge

• The conversion of electric energy

How do conductors differ from insulators in terms of their resistance?

• Conductors have high resistance, insulators have low resistance

• Conductors have low resistance, insulators have high resistance

• Both have the same resistance

• Conductors and insulators do not affect resistance

Where does an electric circuit get its resistance from? (there are 2 main sources)

• Wires and batteries

• Resistors and insulators

• Capacitors and inductors

• Switches and connectors

What happens to the current in a circuit as the resistance gets higher?

• The current increases

• The current decreases

• The current remains the same

• The current fluctuates

What is meant by the word “resistor”?

• A device that stores energy

• A device that opposes the flow of current

• A device that increases voltage

• A device that converts energy
