Electric current
Electrical charge
2.Currents and insulators
Conductors: Cunducts heat and electricity easily. Examples: Gold, cooper, silver...
Insulators: Doesn't conduct heat and electricity easily. Examples: wood, plastic, cardboard...
3.Electric circuits
Conductors: transport the electrical energy: wire
Power sources: supply the necessary electrical energy: cell and battery
Load devcies: recive the electrical energy: motors, lamps and resistors
Control devices: regulate the circuit: Push switch, one-way switches and two-way switch
Representanting circuits: electrical schematics.
Circuits with different components
Different between NO and NC push switches
Circuit with two-way switch
Circuit with multiple load devices
Circuit with multiple control devices
Representation of circuits
Simple circuit with one-way switch and lamp
Simple circuit with with one-way switch and buzzer
Open, closed and short circuits
Short circuit: when the electric currentis transported by the wires without passing trought the load device
Closed circuit: when the power source researches the load devices
open circuit: when the energy of the power cannot reach the load devices
Main electric variables
Ohm's law: ''The current in a circuit is directly proportional to rheelectric potential difference impressed across its ends and inversely proportional to the total resistance offered by the external circuit
Main variables
Resistance: this is the opposition to the flow of the electric current
Voltage: this is the difference between two points (positive or negative)
Current: this is the intensity of the current of amount of electrons flowing through a conductor over a certain time
Types of circuits
Series-parallel combination
Parallel circuit
Series circuit
Solving circuits
8.1. Solving series circuit
8.2. Solving parallel circuits
Converting electric energy
Light We can convert electricity to light
Heat When electrons move trhough a conductor create friction with the material and produce heat.
Motion We can convert electricity to motion by a motor
Sound We can use elctrical energy to transmit dound trhough microphnes
Energy and environment
Environment impact
Responsible use of energy:
Low energy bulbs
Consume less energy
Always switch off electronic equipment
Use domestic appliances only when are full
