ELECTRICITY :bulb: :zap: :electric_plug:
ELECTRICAL ENERGY
Is the most common form of energy because it is easy to obtain.
CONDUCTORS AND INSULATORS
INSULATORS
Are materials that do not let electricity current flow trough them.
CONDUCTORS
Are materials that let electricity current flow trough them.
Comverting electrical energy
light
Motion
also we can comnvert electricity in motion using a motor
Heat
electrons move through a conductor or load device they create friction with the material as they pass througt . This effect is known as the Joule effect
can convert electricity to light through load devices such as incandescent lamps
sound
we can use electrical energy to transmit sounds through microphones and produce sound effects
Energy and the emvironment
transportation and comsuption of electricity have an impact on our enviroment
enviromental impact of enrgy
is the energy generated industrially in power stations many of the stations have an impact on the enviroment
responsible use of energy
when we save energy we save money too but more inportantiy we save natural resources
COMPONENTS OF ELECTRIC CIRCUITS:
POWER SOURCES
LOAD DEVICES
CONDUCTORS
CONTROL DEVICES
OPEN AND CLOSED CIRCUITS
CLOSED CIRCUITS
when the energy of the power source reaches the load devices the circuit is close
the table below shows the schematic
OPEN CIRCUITS
but it can also be because of a fault in the circuit
When you open a circuit the energy cannot
reach the load devices this happen if the switch
is open
Types of circuits
circuits can have diferent characteristics depending on how we arrange the load devices
Series circuits
al the components are conected one after the other . Current flows through all the load devices
Parallel circuits
In these circuits the load devices are connected on different branches they are several posible paths for the electric current
Series-parallel combination
These circuits contain devices connected in series and in pararllel
COMPONENTS OF A CIRCUIT
RESISTOR: A load device that opposes the flow of the electric current.
WIRE: The component that electric current flows through.
BUZZER: Convertselectrical energy to sound energy.
ONE-WAY SWITCH:
MOTOR: Converts electrical energy to light energy.
PUSH SWITCH
LAMP: Convertselectrical energy to light energy.
TWO-WAY SWITCH
BATTERY: A grouped set of cells.
CELL: Supplies electrical energy to the rest of the circuit. They have positive and negative terminals.
