Read electrical schematics read circuit diagram electrical diagram how tos beginners guide how to read electrical schematics posted by james freeman 09 19 2020 electrical schematics are the maps for designing building and troubleshooting circuits learning how to read and understand schematics will be easy for beginners with recognizing basic schematic symbols this tutorial . Zoom in on a specific section of your schematic to examine the different labels for the electrical components if your schematic is especially complex youll see numbers next to the letter abbreviation keep track of these labels to understand which component is which. Resistors on a schematic are usually represented by a few zig zag lines with two terminals extending outward schematics using international symbols may instead use a featureless rectangle instead of the squiggles potentiometers and variable resistors variable resistors and potentiometers each augment the standard resistor symbol with an arrow. Before being able to read a schematic it is necessary to learn and recognize the symbol for each component in a circuit each symbol in a schematic represents a physical electrical or electronic component in the circuit above the schematic is shown on the left and has two symbols representing two components
