Minus to "weight"
Food giving to consumers of a current is made by means of a wire which is always connected by more or less difficult way to the storage battery in what it is possible to be convinced according to electroschemes of the following chapter.
The return chain is provided by electrocarrying-out metal elements of a body or the engine. Thus a large number of expensive copper cable is saved. In most cases the short piece of a cable nevertheless is necessary for a return chain – namely where the consumer of an electricity is located not directly on metal. For this purpose exists – distributed on all body – a certain quantity of so-called points of "weight".
The negative pole of the storage battery too, of course, is connected to a body, "weight" as autoelectricians speak. So remember – «a minus to weight».
