5-2 Voltage Rating

Resistors shall have a rated direct-current (DC)

continuous working voltage or 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:

Where:

E = Rated voltage (V)

E =

R = Nominal

resistance (Ω)
