01
What is an atom?
What is an atom?
It is the smallest particle of a chemical element that can exist.It is composed by the inner shell and the outer shell. The inner shell is composed by the nucleous, wich is formed by protons (positively charged) and neutrons ( they don't have electric charge). The outer shell is composed by the electron orbits and the electrons (negatively charged).
02
what is an electric current?
What is an electric current?
It refers to the amount of electric charge that goes through a circuit. It is measured in Amperes (A) wich refers to the quantity of energy that pases through an especific part of an electric circuit and at an especific period of time.
03
components of an electric circuit
Components of an electric circuit
An electric circuit is a group of several components wich are connected and through wich energy is produced, transported and released in the form of several ways such as light, sound or movement.
Cell/battery:
It is the source of energy.
Connectors:
They connect the different items and act as a conductor to flow electric current.
Key/switch:
It controls the flow of energy.
Electric device:
It recieves the energy and transforms it into light, sound...
04
types of electric circuits
Types of electric circuits
There are several types of electric circuits:
Types of electric circuits: series circuits
The series circuits are those wich are formed by just one "path" through wich all the current goes.In these circuits if one component doesn't work it doesn't let the current pass and the rest of the circuit won't work properly.
Types of electric circuits: parallel circuits
The series circuits are those wich are formed by several branches.
05
ohm's law
Ohm's Law
It's a law formulated by the physic and mathematic Georg Simon Ohm. It was created for us to understand the main fundaments of the electric circuits.
