State
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.
Show
A car battery links several lead-acid cells in series, each contributing about two volts, to reach its rated voltage.
Watch for
Students often picture a battery storing electrons directly, rather than storing chemical reactants that release current on demand.
