Abstract
IN practice, an electrician sometimes merely requires a circuit diagram of the apparatus or equipment with which he is working. He must therefore use symbols to denote electric bells, dynamos, etc., and show how they are connected with the accessory apparatus, such as switches, fuses, and regulating resistance coils. It is of importance that standard symbols should be internationally adopted. Considerable progress has been made in this direction by the International Electro-technical Commission, and the. leading countries of the world have sent in suggested symbols. Complete agreement, however, has not yet been obtained.
