The technical sense ('reversing direction repeatedly') is a direct adjectival/participial use of the verb 'alternate', so learners who know 'alternate' can derive the meaning.

Etymology

Alternating comes from the Latin part alter, which means 'other' or 'one of two', and is the same root you see in alternative. So an alternating current is easy to picture: it 'goes one way and then the other', reversing direction regularly.
