How a Battery Works
Intermediate~20 min14 steps
A chemical reaction kept waiting for a wire — and everything that follows from that.
You’ll learn
- Explain a battery as a redox reaction split into two halves
- Identify the anode, the cathode and what moves between them
- Find the limiting reagent of a reaction from masses
- Predict what wiring cells in series or in parallel does
- Use Faraday’s law to relate charge to the mass that reacts
- Compare alkaline, lead–acid and lithium-ion cells
