5.1 Voltage Rating
Resistors shall have a rated direct current (DC) continuous working voltage or approximate
root mean square (R.M.S.) continuous working voltage at commercial line frequency and w
corresponding the power rating as determined from the following formula:
Where,
E =
√
P x R
E = Rated voltage (V)
P = Power rating (W)
R = Nominal resistance (Ω)
However, if the rated voltage thus
surpasses the specified maximum
voltage, it shall be considered
the rated voltage.
