5-2 Voltage Rating
Resistors shall have a rated direct-current (DC)
continuous working voltage or approximate
sine-wave root-mean-square (RMS) continuous
working voltage at commercial-line frequency
and waveform corresponding to the power rating,
as determined from the following formula:
Where:
E = Rated voltage (V)
P x R P = Rated power (W)
R = Nominal resistance (Ω)
E=√
In no case shall be rated DC or R.M.S. continuous
working voltage be greater than the applicable
maximum value.
