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)

E =

R = Nominal resistance (Ω)

In no case shall be rated DC or R.M.S. continuous

working voltage be greater than the applicable

maximum value.
