About Wira Electrical

Wira Electrical is a free electrical engineering reference built for students, hobbyists, and working engineers who want clear, technically accurate explanations — without the textbook paywall.

Every article is written and reviewed by Wira Adhitama, an electrical engineer with hands-on experience in power systems and circuit analysis. The goal is simple: take the theory that lives in dense academic papers and expensive textbooks, and make it genuinely understandable.

What you’ll find here:

• DC and AC circuit analysis
• Electronics fundamentals (transistors, filters, amplifiers)
• Step-by-step worked examples with real numbers
• Reference material for Ohm’s Law, Kirchhoff’s Laws, nodal analysis, and more

Wira Electrical has been publishing since 2020 and is read by engineers and students worldwide.
