Random
100
This states that like charges repel, or push away, and opposite charges attract.
What is the law of electric charges.
100
This is a material in which charges can move easily.
What is a conductor?
100
This is the rate at which charges pass a given point.
What is an electric current?
100
These are points on a magnet that have opposite magnetic qualities.
What are magnetic poles?
100
This device changes electrical energy into mechanical energy.
What is an electric motor?
200
This is the force between charged objects.
What is an electric force?
200
This is a material in which charges cannot move easily.
What is an insulator?
200
This is a circuit that forms a single loop.
What is a series circuit?
200
This is the region around a magnet in which magnetic forces can act.
What is a magnetic field?
200
This is the process by which an electric current is made by changing a magnetic field.
What is electromagnetic induction?
300
This is the region around a charged object in which an electric force is exerted on another charged object.
What is an electric field?
300
These are electric charges at rest on an object.
What is static electricity?
300
This is a circuit where the loads are connected side by side.
What is a parallel circuit?
300
This is the interaction between electricity and magnetism.
What is electromagnetism?
300
This increases or decreases voltage of an alternating current.
What is a transformer?
400
This is when something becomes charged by direct contact.
What is conduction?
400
This provides the shortest path for charges to reach the ground. It also protects tall buildings from lightning strikes.
What is a lightning rod?
400
This is a measure of how much work is needed to move a charge between two points.
What is voltage?
400
This is a coil of wire that produces a magnetic field when carrying an electric current.
What is a solenoid?
400
This is a device that uses electromagnetic induction to change mechanical energy into electrical energy.
What is an electric generator?
500
This is when something becomes charged without direct contact.
What is induction?
500
This is the loss of static electricity as charges move off an object.
What is electric discharge?
500
This is the opposition to the flow of electric charges.
What is resistance?
500
This is made up of a solenoid wrapped around an iron core.
What is an electromagnet?
500
This type of transformer decreases voltage.
What is a step down transformer?
