Electricity
:fire:
Electrical energy
:!!:
Electricity is a form of energy that lets electrons move from one atom to another
The electric current is the flow of electrons from one atom to another
Conductors and insulators
:unlock:
Conductors: materials that let electricity flow through them
Electrician tools have the handless made up of insulating materials. This is to stop the electric current
Insulators: materials that do not leet electricity flow through them
Electric circuits: Components
An electric circuit is a serie of interconected components that an electrric current flows through to produce an effect
Control devices
One way switch
Conductors
wire
Load devices
Motor
Lamp
Buzzer
Power sources
Battery
Electrical schematics
:explode:
Open and closed circuits
components
Ohm´s law
Current:amount of electrons flowing through a conductor.
Voltage: Is the difference in the charge between two points wich make electrons move
Resistance: Is the oposite to the flow of the electricity current
The current in a circuit is proportional to the electric potential difference impressed across its ends and inversely proportional to the total resist
Types of circuits
:warning:
Series circuits
Parallel circuits
combiation circuits
Converting electrial energy
:star:
light
we can convert electricity to light thanks to load devices such as incandescent lamps, fluorescent tubes and electronic or low-energy lamps
Heat
when electrons move trough a conductor or load devices, they crate friction whit the materials as, they pass through which produce heat
Motion
We can also convert electricity to motion using a motor
Sound
We can use electrical energy to produce sound through microphones and we can produce sound effects trough sirens, buzzers and bells.
