• Kirchhoff’s laws — two-mesh circuit analysis with clear results

• Cable sizing & voltage drop — recommend cross-section and estimate drop

• LED resistor, voltage divider, 555 timer, op-amp, LM317

• Reactance & impedance, RC/RL filters, star–delta transformation

• Three-phase power, transformer calculator, battery life

• AWG wire table, SMD resistor codes, E-series nearest values

• PCB trace width (IPC-2221 style estimate)

• Unit converter with SI prefixes

• Favorites, search, and categorized tools

• Light / Dark / System theme

• Multi-language support

• Optional one-time purchase to remove ads

WHO IS IT FOR?

• Electronics & electrical engineering students

• Makers and DIY hobbyists
