Schematic Symbols

So far, we’ve been using our observational drawing skills to draw our circuits. There are other ways to accurately represent the circuits that we build. We can use schematic symbols to draw our circuits. When we make drawings like these, they are called schematics. This is the way engineers communicate the circuits that they design and create. 

Here is a schematic of the circuit you built with a pushbutton, lightbulb, and batteries. You can draw all of the circuits that you make using the schematic symbols. You can plan the circuits you want to build by first making a schematic drawing - try this for the next circuit you'd like to make.
