3.2 Voltage Rating ：
Rated Voltage: The resistor shall have a DC continuous working voltage or a rms. AC
continuous working voltage at commercial-line frequency and wave form corresponding to
the power rating, as determined from the following
E= Voltage rating (v)
P= Power rating (w)
R= Nominal resistance(Ω)
