Electricity and Magnetism Flashcard

Front

What is the field surrounding a magnet where magnetic forces act?

Back

Magnetic Field: The area around a magnet where magnetic forces can be detected.

Front

What do we call the flow of electric charges from one place to another?

Back

Current: The movement of electric charges, typically measured in amperes.

Front

What is a material that does not allow electric current to flow?

Back

Insulator: A substance that resists the flow of electric current, such as rubber or glass.

Front

What is a material that conducts or transmits electricity?

Back

Conductor: A material that allows electric current to flow easily, such as copper or aluminum.

Front

What type of magnetism is produced by an electric current?

Back

Electromagnetism: The phenomenon where electric current creates a magnetic field.

Front

What is the unit of electric current?

Back

Ampere: The unit of measurement for electric current, symbolized as 'A'.

Front

What is the relationship between voltage, current, and resistance?

Back

Ohm's Law: V = I × R, where V is voltage, I is current, and R is resistance.

Front

What device is used to store electrical energy in an electric field?

Back

Capacitor: A component that stores electrical energy temporarily.

Front

What is the force that opposes the flow of electric current?

Back

Resistance: The opposition to the flow of electric current, measured in ohms.

Front

What is the term for a closed loop through which electric current flows?

Back

Circuit: A complete path that allows electric current to flow.
