Electricity and Magnetism Review

Front

What is electricity?

Back

Electricity is the flow of electric charge, typically carried by electrons, which can be used to power devices and appliances.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source to a device and back.

Front

What is a series circuit?

Back

A series circuit is a type of circuit where all components are connected in a single path, so the same current flows through all of them.

Front

What is a parallel circuit?

Back

A parallel circuit contains two or more branches for current to flow through, allowing multiple paths for electricity.

Front

What is a power source?

Back

A power source, such as a battery, provides a steady supply of electrons to a circuit.

Front

What is oxidation in the context of electricity?

Back

Oxidation is the process that changes the anode metal, making it unstable and releasing electrons that flow through the circuit.

Front

What is reduction in the context of electricity?

Back

Reduction is the process that involves gaining electrons, often occurring at the cathode in a circuit.

Front

What are dry cell batteries?

Back

Dry cell batteries are common batteries that contain a paste or gel instead of liquid, making them portable and easy to use.

Front

What are wet cell batteries?

Back

Wet cell batteries contain liquid electrolytes and are often used in larger applications, like cars.

Front

What is an electric current?

Back

An electric current is the flow of electric charge in a circuit, measured in amperes (A).
