Electrical Energy

Electrical energy is the energy that is carried by electric currents. It is a form of energy that results from the movement of electrically charged particles, such as electrons. Electrical energy is used to power a wide range of devices and systems, from household appliances to industrial machinery.

Key Concepts

1. Electricity: The flow of electrical charge through a conductor, such as a wire.
2. Electrons: Negatively charged particles that carry electrical energy.
3. Circuits: Paths through which electric current can flow, typically consisting of a power source, conductors, and load (device using the electrical energy).
4. Resistance: The opposition to the flow of electric current, measured in ohms.
5. Conductors and Insulators: Materials that allow or resist the flow of electricity, respectively.
6. Transformers: Devices used to change the voltage of electric current for different applications.

Study Guide
