However, I have concerns regarding the discrepancy between simulation results in DC analysis mode and AC analysis mode.&lt;\/p&gt;&lt;p class=&#8221;whitespace-pre-wrap break-words&#8221;&gt;As detailed in the attached document, the resistance value in DC analysis is showing higher than the resistance value in AC analysis (1 Hz), while the inductance values remain almost unchanged. In theory, due to the skin effect, both the wire resistance and inductance values should increase in the order of DC &rarr; AC 1 Hz &rarr; AC 1 kHz and so on.&lt;\/p&gt;&lt;p class=&#8221;whitespace-pre-wrap break-words&#8221;&gt;If you are familiar with the cause of this issue, I would greatly appreciate your insights regarding the reason behind this behavior.&#8221;&lt;\/p&gt;&lt;p class=&#8221;whitespace-pre-wrap break-words&#8221;&gt;The translation maintains the technical accuracy while adapting the polite Japanese business writing style into natural professional English.
