What happens when an electric current flows through a wire
What is a magnetic field forms around the wire
200
Electric Charges can be transferred from object to object but it cannot be created or destroyed.
What is Law on Conservation of Charge
200
Force that causes electric charges to flow. NOTE: Electric charges flow from high to low.
What is voltage difference

What is ask Ms. Novis
300
Resistance is the tendency of material to oppose the flow of electrons. What are three ways one can increase resistance?
What is thinner, longer and hotter wires.
300
One of the bulbs in your Christmas light chain goes out, and so the entire strand goes out.
What is a series circuit
300
A group of atoms with aligned magnetic poles
What is magnetic domain.
300
A device that changes electrical energy into mechanical energy.
What is an electric motor
400
How are conductors and insulators different? Give an example of each.
What is Conductors allow electrons to flow easily through them, like metals. Insulators halt the flow of electrons such as plastic, rubber or wood.
