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 formula as follows:

E = Rated Voltage (V)

P = Power Rating (W)

R = Nominal Resistance (Ω)

E =

√P x R
