Devices Change Electrical Energy
Devices Change Electrical Energy is a skill on Pengi from Session 2: Energy Forms & Evidence in Amplify Science (California) Grade 4.
Key Concepts
Electrical devices function by acting as a bridge between the power source and a useful result. To do their job, they must take in electrical energy (the input ) that transfers through wires and change it into a different form.
This process of changing energy from one type to another is called a conversion . The device converts the invisible electrical input into observable outputs (like motion or sound), allowing the device to perform its intended function.
