Is a form of energy that lets negatively charged particles (electrons) move from one atom to another.
Electrical energy is the most commun form of energy because it is easy to obtain, it can be transported over long distances and it can easily be transformed into many other forms of energy (light, , sound, heat and motion).

Electric Circuit
Is a series of interconnected components that an electric current flows throught to produce an effect .
The main components in a electrical circuit. power sources, conductors, load devices and control devices.
Keywords
Load Device: Component that receives the electrical energy from the power souce and converts it to other types of useful energy.
Control Device: Device that regulates the circuit allowing or preventing the flow of electrical current throught the circuit.

Circuit
A circuit is open when the energy of the power source cannot reach the load the vices,so the electric current cannot flow.
A circuit is closed when the energy of the power source reaches the load devices, so the electric current flows.
Static electricity: is a phenomenon caused bt the accumulation of charge in a material. Electric current is related to moving charges, while static electricity is produced when charges are at rest.
A short circuit: occurs when the electric current is transported by the wires without passing trhough a load device.
Heat: when electrons move through a conductor or load device, they create friction with the material as they pass through, wich produces heat (joule effect).
Motion: the effect obtained when we make an electric crrent flow through a motor is that its a shaft turns in a rotary motion.
-
Sound: The sounds that comes out of a loudspeaker is produced by vibrations in a membrane that are caused by electrical energy.
Main Variables
-
Voltage: is the difference in the charge between twoo points (positive and negative) wich makes the electrons move.
-
For electronics students, Ohm's Law When stated explicitly, it means that voltage = current x resistance, or volts = amps x ohms, or V = A x Ω.
