Electrical Energy

Electrical energy is the energy derived from electric potential energy or kinetic energy. It is a form of energy that is associated with the movement of electric charge. Electrical energy is essential for powering various devices and is a fundamental aspect of modern life.

Key Concepts

1. Electric Charge: The fundamental property of matter that causes it to experience a force when placed in an electromagnetic field.
2. Electric Current: The flow of electric charge through a conductor.
3. Voltage: The difference in electric potential between two points.
4. Resistance: The opposition to the flow of electric current.
5. Ohm's Law: The relationship between voltage, current, and resistance in a circuit (V = I * R).
6. Power: The rate at which electrical energy is transferred by an electric circuit (P = V * I).
7. Energy Efficiency: The ratio of useful energy output to total energy input in a system.
