What we build
We focus on everyday EE workflows: Ohm’s law, resistor networks and color codes, filters, power and battery math, PCB trace width, unit conversions, and related reference tools.
Each tool is designed to be fast, transparent, and usable without an account. Results are for engineering guidance — always verify critical designs against datasheets and applicable standards.
Who it is for
University labs, makerspaces, firmware and hardware engineers, and anyone who needs a reliable second check on circuit math.
Content is published primarily in English, with localized navigation and tool pages in Spanish, Portuguese, French, German, and Japanese.
Independence
ResiCalc is an independent educational project. We are not affiliated with Digi-Key, Mouser, LCSC, or other distributors that may appear as external reference links.
Affiliate or sponsorship relationships, if added later, will be disclosed clearly on the relevant pages.
