Electricity
2. Conductors and insulators
COPPER(Conductor)
PLASTIC(Insulators)
ALUMINIUM(Conductor)
WOOD(Insulators)
SILVER(Conductor)
CARDBOARD(Insulators)
GOLD( Conductor)
Materials that let electric current flow through them are called
Conductors
Materials that do not let electric current flow through them are called
Insulators
Static electricity
:Is a phenomenon caused by the accumulation of charge material.
Electric circuits
: An electric current is aseries of interconnected components that an electric current flows through to produce an effect.
Power Sources
: Components that supply the necessary electrical energy to the rest of the circuit in order to move the electrons
Conductors:
Components that transport the electrical energy from the power sources to the load devices ; In other words, the electric current flows through these components
Load devices:
Components that receive the electrical energy from the power sources and convert it to other types of useful energy
Control Devices:
Devices that regulate the circuit; In other words, They allow or prevent the flow of electric current through the circuit.
Representing Circuits: Electrical schematics.
We represent electrical circuits with a very simple drawing called an
electrical schematic.
Open circuit
Closed circuit
Series circuit: Inthese circuits, all the components are connected one after the other
Parallel circuits: Connected on diferent branches of the wire
Converting electrical energy into:
Light
Heat
Motion
Sound
Energy and responsible use
Low energy bulbs
Consume less energy
Switch off electronic equipment
Use certain domestic appliances when they are full.
Ohm's law
Current I
Voltage V
Resistance R
Is a form of energy that lets negatively charged particles move from one atom to another
Electric current
: Is the flow of electrons from one atom to another inside a conductive material
Electrical energy
: Is the most common 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.
