BASIC ELECTRICITY
-
Electric circuits
An electric circuit is a series of interconnected components that an electric current flows through to produce an effect (like light or motion)
Control devices
Devices that regulate the circuit; in other words, they allow or prevent the flow of electric current through the circuit
Load devices
Components that recibe the electrical energy from the power sources and comvert it to other types of useful energy
-
Power sources
Components that supply the necessary electical energy to the rest of the circuit in order to move the electrons
Electical energy
-
Electrical energy is the most common form of energy, because it is easy to obtain
-
-
Main electric variables
Voltage or potential difference: this is the difference in the charge between two points (positive terminal and negative terminal)
-
Current:Amount of electrons flowing through a conductor over a certain time 
Resistance: this is the opposition to the flow of the electric current
Parallel circuits: in these circuits, the load devices are connected on different branches of the wire. There are several possible paths for the electric current to flow throught
Series circuits: in these circuits, all the components are connected one after the other. This way, all the current flows throught all the load devices
Series-paralell combination circuits: these circuits contain devices connected in series and in parallel

Short circuits
In an electric circuit, a short circuit occurs when the electric current is transported by the wires without passing through a load device
