Regarding the Resistor, this article will explain the information below. Rated VoltageMaximum Working Voltage Rated Voltage and Maximum Working Voltage The data sheet of a resistor lists the rated power, maximum working voltage, and resistance range as shown in the figure above. The rated voltage of a resistor is the maximum value of DC or AC voltage (RMS value) that can be continuously applied to the resistor. The rated voltage can be calculated using the rated power and the resistance value, and is expressed by the following equation: \begin{eqnarray}\mbox{Rated Voltage}{\mathrm{[V]}}=\sqrt{\mbox{Rated Power}{\mathrm{[W]}}×\mbox{Resistance Value}{\mathrm{[{\Omega}]}}}\end{eqnarray} From the above equation, the larger the resistance ...
