Electrical engineering transforms the invisible flow of electrons into the technology that defines modern civilization. Every smartphone, medical device, and spacecraft relies on circuits governed by a handful of elegant laws — Ohm's law, Kirchhoff's rules, and the exponential charging curves of capacitors and inductors. Understanding these fundamentals is the gateway to designing everything from simple LED circuits to complex signal processors.

These simulations let you build and probe circuits without soldering a single wire. Adjust resistance, capacitance, and inductance in real time. Watch voltage and current evolve through RC and RL transients. Explore transistor amplification and operational amplifier configurations that form the building blocks of analog electronics.
