Italian to English Tech/Engineering Electronics / Elect Eng Electrical engineering – circuits

In un circuito elettrico troviamo due elementi: i conduttori e i BIPOLI. Un BIPOLO è un elemento di un circuito da cui escono due morsetti, chiamati anche poli.

I am translating a "quiz" aimed at high school students, so unfortunately have little context beyond this.

Here is a more comprehensive Italian definition.

Translations I have found include two-port circuits and dipoles, but neither make sense considering my source text.

Thank you in advance for your help :))
