Circuit boards resemble model streets with buildings, states the For Dummies website. Circuit boards are thin, flat boards that feature conductors that resemble streets and capacitors, transistors and other electronic components that resemble buildings.
Circuit boards are composed of a number of elements, such as:
- Conductors in silver or copper
- Integrated circuits
The "streets," which are the conductors in silver or copper, run along the underside of the circuit board and connect together the "buildings," which are the different electronic components, states the For Dummies website. The electronic components perform different functions to operate the board, such as restricting or directing the current flow or smoothing out the current, among other functions.
