What is an electric motor?

Back

An electric motor is a device that converts electrical energy into mechanical energy, allowing it to perform work, such as turning a blender or a ceiling fan.

What is resistance in an electrical circuit?

Back

Resistance is the opposition to the flow of electric current in a circuit, measured in ohms (Ω). It affects how much current flows for a given voltage.

Front

What are conductors?

Back

Conductors are materials that allow electrons to flow easily through them, such as metals like copper and aluminum.

Front

What are insulators?

Back

Insulators are materials that do not allow electrons to flow easily, preventing the flow of electric current, such as rubber and glass.

Front

What is voltage?

Back

Voltage is the electric potential difference between two points in a circuit, measured in volts (V). It is what pushes electric current through a circuit.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet that is created by electric current flowing through a coil of wire, which can be turned on and off.

Front

What factors affect the strength of an electromagnet?

Back

The strength of an electromagnet is affected by the voltage of the battery, the amount of material in the core, and the number of loops of wire around the core.

Front

What is current in an electrical circuit?

Back

Current is the flow of electric charge (electrons) through a conductor, measured in amperes (A). It represents how much charge is flowing per second.

Front

What is a switch in an electrical circuit?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electric current.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load (like a light bulb or motor).
