5.1 Voltage Rating

Resistors shall have a rated direct current (DC) continuous working voltage or approximate sine wave

root mean square (R.M.S.) continuous working voltage at commercial line frequency and wave form

corresponding the power rating as determined from the following formula:

However, if the rated voltage thus obtained

surpasses the specified maximum working

voltage, it shall be considered

the rated voltage.
