Ashley is classifying some objects as conductors or insulators. What is the difference between conductors and insulators?
A conductor allows electrical current to flow through it easily, while an insulator does not.
An insulator allows electrical current to move through it easily, while a conductor does not.
A conductor has a static charge, while an insulator does not.
An insulator is a metal, while a conductor is not a metal.
Greg is using a circuit to test materials to determine which ones are good insulators. What happens when he tests a good insulator?
He gets an electrical shock.
No current flows through the circuit.
A strong current flows through the circuit.
The current flowing through the circuit flows weakly and then strongly.
