Voltage rating:
Resistors shall have a rated direct-current (DC) continuous working voltage or an approximate sine-wave root-mean-square (RMS)
alternating-current (AC) continuous working voltage at commercialline frequency and waveform curresponding to the power rating, as
determined from the following formula :
Where : RCWV = Rated DC or RMS AC continuous working voltage at commercial-line frequency and waveform (volt).
In no case shall the rated DC or RMS AC continuous working voltage be greater than the applicable maximum value.
Nominal resistance :
Effective figures of nominal resistance shall be in accordance with E-96 series, and resistance tolerance.
