Unit 5 Review - Electricity/Magnetism

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It consists of a coil of wire, often wrapped around a core of ferromagnetic material.

Front

What is voltage difference?

Back

Voltage difference, also known as electric potential difference, is the force that pushes electric charges to move in a circuit. It is measured in volts.

Front

What particles are found in the nucleus of an atom?

Back

The nucleus of an atom contains protons and neutrons.

Front

What is electric current?

Back

Electric current is the flow of electric charge, typically carried by moving electrons through a conductor.

Front

What is current measured in?

Back

Current is measured in amperes (A).

Front

What is resistance?

Back

Resistance is the opposition to the flow of electric current, measured in ohms (Ω).

Front

What is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of objects, which can cause sparks or shocks when discharged.

Front

What is a generator?

Back

A generator is a device that converts mechanical energy into electrical energy, typically using electromagnetic induction.

Front

What is an electric motor?

Back

An electric motor is a device that converts electrical energy into mechanical energy, allowing it to perform work.

Front

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.
