Car battery + terminal allways biger than - terminal! Why?..

Answer / keith newman

This is to ensure that the battery cannot be connected the
wrong way round i.e +ve to -ve / -ve to +ve. This would
cause serious damage to the alternator and any other
electronic componants fitted to modern cars especialy the
engine management unit.

Car battery + terminal allways biger than - terminal! Why?..

Answer / sanket

become increases hence '+ve' terminal gets thicker than
that of '-ve' terminal width.due to electron losses and
charge flow cycle its widh decreases.
