Understanding Electricity

Dive into what electricity is, how atomic structure creates charge, and how moving electrons form the currents powering our world.

Learn how electrical “pressure” moves charge, drives currents, and how to measure and manage voltage safely in real-world systems.

Understand how electric current flows (amps), how resistance opposes that flow (ohms), and which factors—material, length, and cross-section—affect resistance.

Master V = I × R, learn to rearrange it for practical calculations, and read basic series and parallel circuits.
