## Description

VoltLab is an interactive electricity and circuits lab designed for students, teachers and self-learners. Explore hands-on simulations where you can change component parameters and instantly see how circuit behavior changes. Follow step-by-step lessons, revisit any section at your own pace, and use clear reference materials and formulas to reinforce learning.

Unique quizzes include full solutions and explanations so you learn from every question. VoltLab works offline for study anywhere, offers free access to parts of the content, and supports preparation for lower secondary exams, high-school graduation tests, and university entrance. Download VoltLab to turn abstract formulas into clear experiments and classroom demos.
