Final answer:
Plasma is used in plasma torches for cutting metal, in plasma televisions for displaying images, and in advanced energy research within tokamaks and laser fusion devices.
Step-by-step explanation:
Devices that involve the use of plasma in technology include plasma torches, plasma televisions, and advanced research apparatus such as the tokamak used for magnetic confinement in fusion research, and laser fusion devices used for inertial confinement. A plasma torch, for instance, can generate sufficient heat to cut through metal, while a plasma television utilizes plasma cells that emit ultraviolet light to produce a vivid display of colors. Furthermore, significant scientific endeavors aim to harness plasma for energy production. The tokamak, a device designed for magnetic confinement fusion, confines charged particles with its toroidal coil, creating the extremely high temperatures needed for plasma to exist. Likewise, inertial confinement fusion techniques focus multiple lasers on tiny fuel pellets to achieve the necessary conditions for fusion.
