Study Notes
Understanding Electricity
- Electricity is a complex concept, but it can be broken down into simple components: generators that provide electricity and receivers that receive it.
Generators and Receivers
- Generators provide electricity, such as batteries, accumulators, and piles.
- Receivers receive electricity, such as light bulbs, motors, and computer screens.
Piles and Accumulators
- A pile is a type of generator that uses chemical reactions to produce electricity, but it cannot be recharged.
- Accumulators and batteries can be recharged multiple times before needing to be replaced.
Electric Charges
- Electric charges come in two forms: positive and negative.
- Like magnets, opposite charges (positive and negative) attract each other, while same charges (positive and positive, or negative and negative) repel each other.
Electric Current
- An electric current is a controlled movement of electric charges in the same direction.
- A pile has two terminals: positive and negative, with a difference in electric charge between them.
- When the two terminals are connected, the electric charge tries to balance out, creating an electric current.
Electric Intensity
- Electric intensity is the amount of electric charge moving through a circuit per second, measured in amperes (A).
- The unit of electric intensity is named after its discoverer, André-Marie Ampère.
Electric Tension
- Electric tension is the difference in electric potential between two points, causing electric charges to move.
- The higher the electric tension, the stronger the attraction between opposite charges, resulting in a more intense electric current.
- Electric tension is measured in volts (V).
Schematic Diagrams
- On a schematic diagram, the direction of the electric intensity arrow is opposite to the direction of electron movement.
- This convention was established by early physicists, who thought electrons moved from positive to negative.
- In reality, electrons move from negative to positive, but the conventional notation is still used.
