A continuous path through which electric charges can flow.
What is an electromagnet?
A magnet created by passing an electric current through a coil of wire.
What is a magnetic field?
A region around a magnet where the magnetic force is exerted.
What is the difference between static and current electricity?
Static electricity is a buildup of electric charges on the surface of an object, while current electricity is a flow of electric charges through a conductor.
What is voltage?
The measure of the electric potential difference between two points in a circuit.
What is resistance?
The measure of the opposition of current flow in a circuit.
What is Ohm's law?
The current through a conductor between two points is directly proportional to the voltage across the two points.
What is a transformer?
A device that increases or decreases the voltage of alternating current.
What is electromagnetic induction?
The production of an electric current in a conductor when there is a change in the magnetic field around it.
What is a generator?
A device that converts mechanical energy into electrical energy.
What is a motor?
A device that converts electrical energy into mechanical energy.
What is a solenoid?
A coil of wire with an electric current flowing through it that produces a magnetic field.
What is Faraday's law?
The amount of electromagnetic induction is directly proportional to the rate of change of the magnetic field.
What is Gauss's law?
The electric flux through a closed surface is proportional to the net electric charge inside the surface.
What are the two types of charges?
Positive and negative.
