Aroa garcía saiz y Leire uriarte canales
Electricity
is a form of energy that lets negatively charged particles move from one atom to another
Electric currents
is the flow of electrons from one atoms to another inside a conductive material
conductors and insulators
Insulator
materials that do not let current flow thought them ej: copper
Conductor
materials that let electry current flow trought them ej: wood
Electric circuits
Is a series of intercinected components that an electric current flows through to produce an effect.
Components
Power souerces
Is a supply necessary electrical enrgy
Conductors
Can trasport the electrical energy
Load devices
They reciv the electrical energy
Control devices
They regulate the circuit
Tipes of circuits
Open circuit: when the energy of the power source can not flow
Closed circuit: when the energy of the power source reaches the load devices, so the electric currents
components of a circuit
load devices
Lamp
Motor
Buzzer
Resistor
conductors
Wire
power sources
Cell
Battery
control devices
One-way switch
Push switch
Two-way switch
Types of circuits
parallel circuit: the load devices are connected on diferents branches
combination circuits: contain devices connected in series and in parallel
series circuit: all the components are conected one after the other
Converting electrical energy
Heat
When the electrons move through a conductor or a load device, they create friction with the materials as they pass through, which produces heat.
Motion
We can also convert electricity to motion using a motor.
Light
We can convert electricity to light through load devices such as incandescent lamps, flourescent tubes and electronic or low-energy lamps.
Sound
We can use a electrical energy trasmit sounds through microphones and we can produce sound effects through sirens, buzzers and bells.
Load device
Resistor
Converts energy to light energy
Lamp
Converts energy to kinetic energy
Motor
Converts energy to heat energy
Buzzer
Converts energy to sound energy
