The white wire is the neutral wire which takes any unused electricity and current and sends them back to the breaker panel. The plain or it can sometimes be green wire is the ground wire which will take electricity back to the breaker panel then outside to a rod thats buried in the ground.

Since those appliances dont require a neutral but use two current carrying conductors and a ground wire an electrician may repurpose the white to carry the secondary phase also called a.
According to standards in use since the mid 1900s a wire color code identifies the purpose of each wire in an electrical circuit.

Two of the conductors in nmb cable are covered with plastic insulation one white the other black.
