BASIC ELECTRICITY
Converting electrical energy
Motion
Sound
Heat
Light
Open circuits and closed circuits. Short circuits
Open circuit
Circuit status: Off: thr lamp isn´t lit. The electric current doesn´t flow.
Closed Circuits
Circuit status: On: the lamp is light. The electric current flows and reaches the lam to light it.
Short Circuits
Occcurs when the electric current is transported by th wires without passing through a load device.
Types of circuits
Series circuits
Parallel circuits
Series-parallel combination circuits
Electricity:
form of energy that lets negatively charged particles (electrons) move from one athom to another.
Electric current is the flow of electrons from one atom to another inside a conductive material.
Conductors and Insulators
Conductors
Materials that let electric current flow through them
Examples: Cooper, tin, aluminium ...
Insulators
Materials that don´t let electricity current flow through them
Examples: Wood, plastic, cardboard...
Electric circuits. Components
An electric circuit is a series of interconnected components that an electric current flows through to produce an effect.
Main components
Load devices
Receive the electrical energy
Control devices
Regulate the circuit
Conductors
Transport the electrical energy
Power sources
Supply the necessary electrical enrgy
Main electric variables. Ohm´s law.
Three main varibles:
Current
Voltage ( or potential difference )
Resistance
I=V/R
This equation is known a Ohm´s law, which states:
´´ The current in a circuit is directly proportional to the electric potential difference impressed across its ends and inversely proportinal to the total resistance offered y the external circuit´´
Series and paralel circuits formulas
Series circuits formulas
Parallel circuits formulas
Energy and the enviroment
responsible use of electrical energy
environment impact of energy production and transmission
Representing circuits: electrical schematics
we represent electrical circuits with a very simple drawing called an electrical schematic. Every component in a circuit has a standardiset symbol
