THE BATTERY SYMBOL
Curious" writes: "It is customary to represent a battery in a wiring diagram by thick and thin strokes. Is there a fixed convention as to which stroke represents the'positive side?"— The general, and probably universal, custom is to represent the zinc or negative side of the battery by the thick stroke, and the positive by the thin one. lne conventional sign is thus a fair representation of the out-of-date, but once highly approved, Grove cell, which had a thick zinc plate and a thin and much larger platinum element. Most intelli-gently-drawn diagrams use the plus and minus signs, either instead of the battery symbol, or with it, and the practice is certainly to be commended-.
