I did not find in fritzing a input voltage source at 12V CC to use in my voltage divisor.
Please, tell me where I can find it and how to register in the fritzing available parts to use whenever I need, please.
I am from Brazil.
More information on exactly what you want would be required to do much of anything. It is unclear what a 12V CC refers to. A link to a web site that describes the part you want with physical dimensions and connector definitions would be required to see what is available. A google search of the form “fritzing part part_description” such as “fritzing part 12V CC power supply” will usually turn up any available parts.

There are generic power supply symbols in the core bin, schematic section
