Figure 2.24. This is the schematic symbol for a transformer. There are two connection points on the left. A line from the top point starts making little curly cues which resembles a side view of a coil of wire in open air. The bottom connects to the bottom connection point. This symbolizes one of the windings on the transformer. The left hand winding is usually the primary. To the right of the coil are two parallel vertical lines not touching the coil and not touching each other. They are the same length as the coil. These lines symbolize the iron core on which the two coils are wawnd. To the right of the two lines is another coil with its curly cues facing the other way. Two connection points on the right connect to the two ends of the right hand coil. This symbolizes the second winding of the transformer. The secondary is usually shown on the right. On this symbol there are 3 curls on each coil. The number of curls is sometimes related to the number of turns on the transformer winding and sometimes not. If it is necessary to draw more coils as in a transformer with two secondary windings, The two parallel lines are extended and the two windings are drawn one above the other on the right hand side of the core symbol. In the future the word, quote, transformer, end quote, will suffice to describe this symbol. End verbal description.
