Flow charts help a troubleshooter follow a logical path when trying to solve a problem. A flow chart is a diagram that shows a logical sequence of steps for a given set of conditions.Block diagrams are used with schematic diagrams to help troubleshoot a system, such as a regulated power supply. The primary function of a block diagram is to show how the distinct parts of a system relate to each other. A block diagram is a diagram that shows the relationship between individual sections, or blocks, of a circuit or system.A line diagram, on the other hand, often shows multiple lines leading to or from a component (parallel connections). One-line diagrams have only one line between individual components. A one-line diagram is a diagram that uses single lines and graphic symbols to indicate the path and components of an electrical circuit. Line diagrams are often incorrectly referred to as one-line diagrams.Line diagrams provide a fast, easy understanding of the connections and use of components. A line diagram is used to show the relationship between circuits and their components but not the actual location of the components. A line (ladder) diagram is a diagram that shows the logic of an electrical circuit or system using standard symbols.Schematic diagrams are not intended to show the physical size or appearance of the device. Schematic diagrams are intended to show the circuitry that is necessary for the basic operation of a device. Schematic diagrams do not show the physical relationship of the components in a circuit. A schematic diagram is a diagram that shows the electrical connections and functions of a specific circuit arrangement with graphic symbols.Wiring diagrams often include details of the type of wire and the kind of hardware by which wires are fastened to terminals. Wiring diagrams show, as closely as possible, the actual location of each component in a circuit. A wiring diagram is a diagram that shows the connection of all components in a piece of equipment.An abbreviation is a letter or combination of letters that represents a word. Symbols are used to represent electrical components of electrical and electronic diagrams. A symbol is a graphic element that represents a quantity or unit.Pictorial drawings show physical details of an object as seen by the eye. A pictorial drawing is a drawing that shows the length, height, and depth of an object in one view.Identify the differences between pictorial drawings, wiring diagrams, schematic diagrams, line diagrams, block diagrams, and flow charts. Electrician trade always ask about symbol because symbol is a very important part of electrician trade with thorough knowledge of electrician a candidate can never work properly and safely without good knowledge of symbol is….
