Z (impedance) can be calculated from Z = RX / (R + X) C and the ex electrostatic field version, where R can be calculated from the ex electrostatic current version!
Impedance has frequency characteristics. In an equivalent circuit, it can be represented as a parallel circuit of the resistance R and the capacitance C. In an alternating current field, when the frequency is low, current flows through the R part, and as the frequency increases, current flows through the C part. For more details, please refer to "NO.161 Frequency Characteristics of Impedance" on [Analysis Know-How.com]. Here are the key points: - Impedance has frequency characteristics. - Resistance R can be derived from conductivity σ. - Reactance X = 1/ωC can be derived from permittivity ε. - Z (impedance) is given by Z = RX / (R + X). - C can be calculated from the electrostatic field version. - R can be calculated from the electrostatic current version.

Company information
With a motto of 'swift response and provision of cutting-edge technology,' our experienced technical staff directly provides services aligned with the company's timeline. We aim to contribute to researchers and engineers in the R&D and design departments by incorporating the latest technologies, which are gaining attention at academic societies such as the Institute of Electrical Engineers, into our software, and by continuously disseminating state-of-the-art tools and information. ■ For customers who are not experts in analysis μ-EXCEL is an easy and fast analysis software for initial assessments. The concept is to simplify operations as much as possible and quickly produce results to first determine the validity of ideas. Additionally, we offer a subscription service that lowers the barrier to entry. For a monthly fee of 9,800 yen, users can access unlimited use, with options for monthly subscriptions only when needed, and the ability to resume at any time. As part of our comprehensive support system, "Analysis Know-How.com" was created. It compiles an overview of analysis tasks and techniques into short videos. Users can efficiently search during their spare time on their smartphones. If you still have questions, please send your Excel file as an email attachment, and our experienced supporters will review it and provide answers. ■ For customers who want to delve even deeper We are expanding our business into specialized themes.
