Step up and Step down
Electrical current is the flow of moving _______________.
electrons.
Describe electrons in a material that conducts electricity vs electrons in an insulator.
Electrons in insulators are tightly held to the atom and do not easily move.
Describe a series vs a parallel circuit. And what happens if a lightbulb is removed from each.
Series - bulbs are in a row.
Parallel - multiple paths for electricity to flow.
Series - all bults stop working
Parallel - other bulbs continue working
