Looking at a schematic, also known as an electrical diagram, for the first time can be overwhelming. There are so many little symbols in close proximity and it can all look quite confusing to say the least. Here are some tips that can have a beginner soon reading a diagram like a Professional Electrician From Hoppers Crossing.
First of all, you will want to learn what all those little symbols mean. Rather than making things complicated, these little icons actually simplify things when you know what you’re looking at. There is a long list of symbols that can be used in these diagrams, and if you are looking at a complex schematic then it is a good idea to do some wider research so you can get a visual. However, there are some basic and commonly used symbols that are bound to pop up, and some you may even vaguely remember from high school science classes.
Lines represent wires, and these connect the devices. Crossing on the diagram does not necessarily mean wires connecting. If they do connect, the intersection of lines will be punctuated with a back circle. If they do not connect, there should be a slight gap so that the lines do not actually cross, or a semi-circle indicating one over the other but no connection. The first symbol to learn is the battery or cell, an icon which consists of two vertical lines with one being slightly shorter than the other. The longer of the two is the positive anode and the shorter is the negative. This polarity should be able to help you in determining the flow as well, and applies across other devices as well. Things such as capacitors and diodes can also follow this rule.
If you see a similar symbol to the cell, but one of the lines is curved in a C shape, then this is a capacitor. This device stores energy in an electrostatic field. A switch is another popular symbol, demonstrated as two little circles on a line. When the switch is open, the line between the circles is at an angle, like an open doorway. This clearly disrupts the continuous line of electricity, and so a switch must be closed or ‘on’ in order for the circuit to operate. A resistor is a zig zag line, and this one appears in almost every circuit you will come across. The function of a resistor is to dissipate the energy so that the circuit does not drain your battery. Power is a single vertical line with a small circle on top, while ground is a vertical line with two or three lines in an inverted pyramid beneath it. Inverters, transistors and diodes are also common icons which you may come across, and it is better to see an image to compare it to. Consult the manufacturer’s data sheet for exact functions and measures of each device.
Once you have a general understanding of some of the functions of items within the diagram, you will begin to be able to read the entire thing. In almost all cases, a schematic is read left to right and top to bottom. This is the industry standard for the flow of current.
While this is far from a definitive guide, it will help you to see that a schematic doesn’t have to be so daunting once you know a little more about it. Of course, if you require in depth electrical work then it is always best left to the professionals.
