True or false? Photons are exchanged between charged particles.
neutrons, protons, electrons
What are atoms composed of?
True or false? Protons are negatively charged.
True or false? Electrons are negatively charged.
True or false? Neutrons are positively charged.
The amount of charge that travels past a fixed point in an electric circuit each second.
What is an electrical current?
From the negative to the positive
Which direction does an electrical current run?
The ability of a material to impede the flow of charge.
What is resistance?
True or False? Resistance can be used to create heat and light.
True or False? Electrical devices "use up" electrons.
The collisions electrons experience result in energy which creates heat.
What goes on inside an electrical device?
A circuit that does not have a complete connection between the two sides of the power source.
What is an open circuit?
What are the two types of circuits?
the movement of charged particles.
Finish the sentence: All magnetic force results from...
True or false? The more electrons that are aligned, the less the magnetic force.
The exchange of photons
What causes electromagnetic force?
Charging an object without direct contact between the object and a charge.
What does it mean to charge by induction?
Charging an object by allowing it to come into contact with an object that already has an electric charge.
What does it mean to charge by conduction?
Current that flows from the positive side of the battery to the negative side.
What is a conventional current?
The flow is in the motion of the electrons in its atoms.
Where is the charged particle flow in a permanent magnet?
