This International Standard lays down rules for signs and reference directions and reference polarities for electric currents and voltages in electric networks, as well as for the corresponding quantities in magnetic circuits.
In Clauses 3 to 9, the time dependence is arbitrary. Clause 10 details the rules and recom-mendations for complex notation.
