Answer 1

The correct answer is conductors.Key Points

Conductors are materials that allow electric current to pass through them easily, due to the presence of free electrons in their atomic structure.
These electrons are not bound to any particular atom and can move freely within the material when a voltage is applied.
Examples of common conductors include metals like copper, aluminum, and silver, as well as some non-metals like graphite (used in pencils) and plasma (found in lightning bolts and some types of lamps).

Additional Information

Insulators are materials that do not allow electric current to flow through them easily.
- They have few free electrons and a high resistance to electrical flow.
- Examples include rubber, glass, and most plastics.
Alternators are devices that convert mechanical energy (e.g. from an engine or turbine) into electrical energy, by using rotating magnets to induce a current in a stationary coil of wire.
- They are commonly used in cars and power plants.
Capacitors are electronic components that store electrical energy in an electric field.
- They consist of two conductive plates separated by an insulating material (dielectric), and can be used in circuits for filtering, timing, and energy storage.
