Jadaühenduses läbib kõiki takisteid sama nimivool, mille tõttu tööpiiride ohutuks määramiseks, nt takisti ülekuumenemise ärahoidmiseks, kasutatakse jadaühenduses olevate takistite nimivoolu korral madalaimat nimivoolutugevust omavaid takisteid.
In a series connection, the same rated current passes through all resistors, which is why, in order to safely determine operating limits, e.g. to prevent the resistor from overheating, the resistors with the lowest rated current are used for the rated current of resistors in the series connection.
