What is Electricity?
Electricity is the flow of electric charge. This flow occurs due to the movement of electrons through a conductor, driven by a difference in electrical potential energy, or voltage. When electrons move through a conductor, such as a wire, they create an electric current Dioda.
Key Electrical Terms
Voltage (V): The difference in electrical potential energy between two points in a circuit, measured in volts.
Current (I): The flow of electric charge through a conductor, measured in amperes (amps).
Resistance (R): The opposition to the flow of current in a circuit, measured in ohms.
Power (P): The rate at which electrical energy is transferred by an electric circuit, measured in watts.
Types of Electrical Circuits
Understanding different types of electrical circuits is crucial for learning about electricity:
Series Circuits
In a series circuit, components are connected end-to-end, forming a single path for the current to flow. If one component in the series fails, the entire circuit is broken, and the current stops flowing.
Parallel Circuits
In a parallel circuit, components are connected across common points, creating multiple paths for the current to flow. If one path fails, the current can still flow through the other paths, making parallel circuits more reliable for most practical applications.
