Students are introduced to several key concepts of electronic circuits. They use the hands-on associated activity to learn about some of the physics behind circuits, the key components in a circuit and their pervasiveness in our homes and everyday lives. Students learn about Ohm's law and how it is used to analyze circuits.
To design and create the endless number of devices and processes that use electricity and circuits, engineers require a basic understanding of electricity and the physics behind circuits. Electrical engineers design the circuitry for the products we use every day. They also design computers and telecommunication devices, lighting and wiring for buildings, and operating electric power stations. Electrical engineers address energy conservation in our homes and businesses by developing better ways to design and implement circuits and electronic devices to efficiently use and ultimately save energy.
After this lesson, students should be able to:
- Define electric current and voltage.
- Explain the relationship between voltage, current and resistance (Ohm's law).
- List several different circuit components.
