200
The voltage difference in potential between two points in a circuit
What is a potential difference?
300
If many electrons jump from one substance to another, this is created.
What is a spark?
300
The conditions that limit the flow of electrons in an electric circuit.
What is resistance?
300
Type of circuit that contains separate branches for current to move through.

What is an electric field?
400

What is 1 & 2?
500
Why aren't all items magnetic? What makes iron, cobalt nickel magnetic?
What is most atoms have paired electrons, so their magnetic fields cancel out. Iron, cobalt, and nickel do not have all paired electrons, so the magnetic field stays.
