Electricity and Magnetism

Front

What is a material through which electrons can easily flow?

Back

Conductors are materials that allow the flow of electric current due to the presence of free electrons.

Front

What are the two ends of a bar magnet called?

Back

The two ends of a bar magnet are called Magnetic poles.

Front

What is a broken loop of conductors called?

Back

An open circuit is a broken loop of conductors that prevents the flow of electric current.

Front

What does the symbol in a circuit drawing that represents a battery look like?

Back

The symbol for a battery in a circuit drawing typically consists of two parallel lines, one longer than the other.

Front

Why are wires covered in plastic?

Back

Wires are covered in plastic to prevent electric shock and to insulate the wire from external elements.

Front

What is the difference between a closed circuit and an open circuit?

Back

A closed circuit allows electric current to flow, while an open circuit does not due to a break in the loop.

Front

What is the role of a switch in an electrical circuit?

Back

A switch is used to open or close a circuit, controlling the flow of electricity.

Front

What is an insulator?

Back

An insulator is a material that does not allow electrons to flow freely, preventing the flow of electric current.

Front

What is the function of a light bulb in a circuit?

Back

A light bulb converts electrical energy into light energy when current flows through it.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects, often caused by friction.
