Chemistry / Unit 11 Chem 2210 short lesson, about 20 seconds
Battery as a Multi-Cell Galvanic Device
Captions available
The idea
A battery is a self-contained device built from one or more galvanic cells delivering a stated voltage and current, taught here as mechanism only.
In practice
A car battery links several lead-acid cells in series, each contributing about two volts, to reach its rated voltage.
Where people slip
Students often picture a battery storing electrons directly, rather than storing chemical reactants that release current on demand.
