The Three-Electrode Cell Explained in 90 Seconds

Описание: Unlock the fundamentals of modern electrochemistry in just 90 seconds.
This video breaks down the three-electrode cell—the working, reference, and counter electrodes—along with the role of electrolytes and potentiostatic control.

You will learn:
• What each electrode does and why its surface matters
• How electrolytes transport ions (not electrons)
• Why reference electrodes must remain stable
• How the potentiostat controls potential and measures current
• How these components come together to enable real electrochemical experiments

Perfect for students, researchers, and anyone starting out in electrochemical methods such as cyclic voltammetry, battery testing, or redox kinetics.
