[Audio] Computing Creative Design and Innovation.

[Audio] Electricity and Electronics. Electricity and Electronics.

[Audio] Objectives By the end of the session students will be able to, 1 Understand what are electrical systems? 2 Draw electrical circuit schematic diagrams using standard symbols..

[Audio] Keyword Atoms the building blocks of life..

[Audio] What is electricity?. What is electricity?.

[Audio] Almost every household appliance you have used before relies on electric circuits for their operation..

[Audio] Such devices include torches, mobile phones, iPods, room lights, or TV sets.

[Audio] You already know that you need a battery or power switch to turn on these appliances to make them ' work'..

[Audio] You may not be able to 'see' electricity, but we see its effect every day!.

[Audio] Nowadays, you use electricity for everything, including cooling, heating, and lighting systems..

[Audio] You use it to power laptops, mobile phones, and other home appliances. Electricity is also used in transportation systems..

[Audio] For example, cars use electricity stored in their batteries to power the engine and drive the wheels..

[Audio] But have you ever wondered how electricity really works?.

Atoms. Text Description automatically generated.

[Audio] Atoms are the building blocks of life. Atoms.

[Audio] Atoms You and everything around you is made up of atoms..

[Audio] Atoms You cannot see them because they are very small. They are almost 400 million times smaller than a golf ball..

[Audio] The structure of an atom consists of three main parts: • Protons • Electrons • Neutrons.

[Audio] Atoms The most important part of an atom is the electron..

[Audio] Atoms Electrons are charged particles that can move between atoms.

[Audio] Atoms The movement of the electrons, or the flow of electrons, is called 'electric current..

[Audio] Atoms This creates an electric charge, which is used to feed and make electronic devices work..

[Audio] Atoms The electric current is what gives us electricity..

[Audio] electrical sources The current generated by electrical sources can either be direct current ( DC) alternating current ( AC)..

[Audio] direct current (D A direct current is one that is steady, constantly going the same way around a circuit, from positive to negative..

[Audio] direct current ( DC). direct current (DC).

[Audio] alternating current ( AC). An alternating current is one that continuously changes its direction, going back and forth around a circuit..

[Audio] alternating current ( AC).. alternating current (AC)..

[Audio] What is an electric circuit? An electrical circuit is the path in which electrical current can flow. Depending on the function of the electrical circuit, it can be very complicated or very simple.

[Audio] What is an electric circuit? Basic circuits are made of the following parts: 1. voltage source (e.g., battery) 2.conductive path (e.g., electric wires) 3. load (electrical component) 4. switch.

[Audio] What is an electric circuit? The voltage source moves the electric current..

[Audio] What is an electric circuit? The current travels through the conductive path. This is a path that allows electricity to pass through it (e.g., copper wire)..

[Audio] What is an electric circuit? The current feeds the load (e.g., a light bulb). This load consumes electrical power and transfers it into a different form of energy (e.g., light, heat, mechanical etc.)..

[Audio] What is an electric circuit? The switch is a small gap in the circuit that is used to open or close a circuit.

Circuit diagrams. Text Description automatically generated.

[Audio] Pictorial circuit diagram Using realistic pictures to represent the components of an electrical circuit.

[Audio] Schematic circuit diagram Using graphic symbols to represent the components of an electrical circuit.

[Audio] Circuit diagrams Circuit diagrams are used for the design, construction, and maintenance of electrical and electronic equipment..

[Audio] Circuit diagrams They show the relative positions of the electronic components and their connections to one another. They are often used to provide a visual representation of the circuit to electricians and engineers.
