Before use in both domestic and industrial settings, the dangerously high voltage is reduced to a safer, more manageable level. Moving charge creates an electromagnetic field. The change in direction of the charge in AC gives rise to the emission of electromagnetic waves, and these form part of the electromagnetic spectrum ( Figure 8.3 ).
