What is the difference between working voltage and dielectric withstanding voltage in resistor components? Or both the working voltage and dielectric withstanding voltage is same? Can I apply the working voltage value to the dielectric withstanding voltage?

    \$\begingroup\$ It depends on what you mean by working voltage - a spark plug's working voltage is potentially larger (when initiating an arc) than the dielectric of the gas between electrodes. \$\endgroup\$ – Andy aka Aug 17 '18 at 10:10

Working voltage: Voltage that the device can safely and reliably be used.

Dielectric Withstanding Voltage: Voltage at which the device exhibits breakdown such as arcing or degradation of materials.
