7. Why learn electronics? Because it explains how things actually work Electronic devices are made from electronic components. These components have capabilities and limitations. You learn how to fix things (it’s practical) You learn problem solving and troubleshooting skills. You develop mechanical aptitude by working with your hands. 6 Copyright © Texas Education Agency, 2013. All rights reserved.

8. Why learn electronics? (cont’d) Electronics is a practical application of math and physics (science) You learn math and science better by applying it. It provides a foundation for engineering and other technical fields. You will be considered smart. Most important: It’s fun and exciting! 7 Copyright © Texas Education Agency, 2013.
