Electricity Basics
The flow of electric charge through a material current?
What is current?
A path along which electric charges can flow.
What is a circuit?
This household device uses a glowing wire to convert electrical energy into light.
What is a lightbulb?
Region around a magnet where magnetic forces act.
What is a magnetic field?
A magnet created by running electric current through a coil of wire.
What is an electromagnet?
Material that allows electricity to flow easily
What is a conductor?
A circuit where all components are arranged in a single path.
What is a series circuit?
The reason power lines are made of metals like aluminum or copper.
What is because they are good conductors?
The ends of a magnet where the magnetic force is strongest.
What are the poles?
Device that uses rotating wire and magnets to produce electricity.
What is a generator?
The buildup of electric charge on an object static electricity?
What is static electricity?
A circuit where components are arranged on multiple branches.
What is a parallel circuit?
This medical machine uses powerful magnets to create images of the inside of the body.
What is an MRI machine?
A material that can be attracted by a magnet.
What is a ferromagnetic material?
Device that uses electricity to produce motion.
What is an electric motor?
The push or pressure behind the flow of electric charge.
What is voltage?
The opposition to the flow of electric current.
What is resistance?
This safety feature melts or shuts off power when too much current flows.
What is a fuse or circuit breaker?
The invisible lines that map the strength and direction of magnetic forces.
What are magnetic field lines?
The process of generating electric current using a changing magnetic field.
What is electromagnetic induction?
Subatomic particle responsible for negative electric charge.
What is the electron?
Device that opens or closes a circuit.
What is a switch?
Wireless charging devices use this electromagnetic process to transfer energy without direct contact.
What is induction (electromagnetic induction)?
Magnetic phenomenon caused by the motion of electric charge inside materials.
What is domain alignment?
Name of the scientist who discovered electromagnetic induction.
Who is Michael Faraday?
