Power Rating

Resistors shall have a power rating based on continuous full load operation at an ambient temperature of 70°C

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 commercial line frequency and waveform corresponding to the

power rating , as determined from the following formula:

RCWV = √ P x R

RCWV = Rated DC or RMS AC continuous working voltage at commercial-line frequency and waveform (Volt)

P = Power Rating (watt)

R = Nominal Resistance (ohm)
