This is the result of a buildup of excess electric charge on an object.
What is static electricity?
This is the net movement in a single direction of an electric charge.
What is current?
This is the type of circuit through which current only has one path to travel.
What is a series circuit?
This is the property of some objects to emit an attractive or repulsive force.
What is magnetism?
These are materials that allow electrons to flow through them easily.
What are conductors?
These charges repel each other.........whereas, these charges attract each other. Say them in order please.
What is like charges repel and opposite charges attract?
This is the "push" that causes charge to move.
What is voltage difference?
This is the type of circuit that contains more than one path through which current to travel.
What is a parallel circuit?
In a magnet, the forces are strongest at these 2 points.
What are the poles?
These are materials that block the flow of electrons through them.
What are insulators?
The 3 ways to transfer charge: through direct contact, rubbing and across a field.
What are conduction, friction, and induction?
This is a closed path an electric current flows through.
What is a circuit?
These are some differences between series and parallel circuits. Name at least 3.
What is: one branch vs. multiple; simple vs. complex; all components MUST work at same time vs. one can work at a time; more increase vs. decrease resistance; voltage decreases as it travels vs. stays the same; current is the same throughout vs. splits
True or False: Magnetic poles CAN be isolated. Explain.
False. If a magnet is broken the pieces each now have their own north and south pole.
When excess charge is removed, we say that the object is this....
What is "neutralized?"
A sudden flow of electric charge due to a charge build up between 2 objects and an example of this.
What is static discharge. Ex.: Lightning
These devices change chemical into electrical energy.
What are batteries?
ATTENTION NEW CONCEPT: These are 2 ways to prevent a circuit from over heating due to too much current.
What are fuses and breaker switch? Fuses melt when overheated to open the circuit. Breakers bend to open the circuit when too much current is available.
This is the feature in the Earth that allows the Earth to act as a giant bar magnet with its own magnetic field.
What is the Earth's core which is made up of various magnetic materials.
The amount of current is directly proportional to the voltage difference.
What is Ohm's Law: V = IR
THIS is the transfer of electric charge away from an object by directing the flow of electrons towards another object, and THIS is an example of the redirection.
What is grounding? What are lightning rods?
This is the tendency of a material to oppose the flow of electric current.
What is resistance?
True or False: It is possible to combine a series circuit with a parallel circuit.
True.
This is the phenomenon that occurs when non magnetic objects are placed in a strong magnetic field. Remember the nail, the wire and the battery.
What is ferromagnetism?
NEW CONCEPT: THESE melt when there is a power surge.....and THESE bend when there is a power surge. Both of them open the circuit to prevent damage to circuits/appliances.
What are fuses and breakers?
