Electricity
Types of circuits
-
-
Short circuits: Occurs when the electric current is transpoted by the wires without passing trough a load device
Series circuit: In these circuits , all the components
Parallel circuits: in these circuits, the load devices are connected on diferents branches of the wire.
Series-parallel combination circuits: this circuits contain devices conected in series and in parallel.

Main electrics variables
Voltage: the diference in the charge between two points, wich makes the electrons move. We measure with volt (V).
-
Current: the intensiti of the current or the amount of electrons flowing through a conductor over a certain time. We measure whith ampere or amp (A).
-
Definition: Electricity is a form of energy that lets negatively charged particles move from one atom to another.
-
Enviroment impact of energy production and transmition: electrical energy is generated industrially in power stations, wich convert a form of energy to electrical energy. Many power stations have an impact on our enviroment because they pollute the atmosphere…
The use of renewable engenires is being promoted as a green alternative to conventional power stations.
Responsible use of electrical energy: when we save energy, we save money too but more importantly, we save natural resources and help to protect the enviroment. This is why we need to consume responsibly and only use the energy we need and always in moderation.
