Electrical Circuits, Construction Materials, and Tiles
Electrical Circuits
Electric current is formed by electrons jumping from one atom to another, and this movement generates electricity.
Voltage is the potential difference that makes the electric current flow through a conductor. A potential difference, tension, or voltage must exist for electric charges to move through a conductor in a given time.
Ohm’s Law
- Current = Amps = I
- Voltage = Volts = V
- Resistance = Ohm = R
In a continuous electric circuit, electrical power is produced by the movement of electrons. These leave the positive pole and go to the negative pole of the battery.
Circuit Types
- Series Circuit: An electric circuit mounted in series. If one component breaks down, the entire circuit stops working, similar to opening a switch.
- Parallel Circuit: A circuit mounted alongside each other. Each component operates independently. If one fails, the others continue working.
- Mixed Circuit: An electrical circuit where some receivers are mounted in parallel and in series.
Construction Materials
Concrete, Concrete, and Mortar
Concrete is a mixture of cement, sand, gravel, and water. Reinforced concrete uses steel rods, forming beams and pillars with a cast that shapes the beam or pillar.
Mortar is a mixture of cement, water, and sand.
Steel in Buildings
Steel structures are fast to assemble by soldering, without waiting for concrete to harden. A drawback is that it is very expensive.
Ethernet frames are used to set the steel to the seed.
Floors
Floors are constructed with plates, beams, and columns.
Prestressed concrete is characterized by a mass of concrete with high-strength steel bars pre-tensioned to increase resistance to flexion.
Plaster
Plaster is a material extracted from rock containing gypsum. It is a white powder that quickly hardens when water is added. It is used to cover brick holes. There are two types: thick (coarse) and fine (but expensive).
Cement
Cement consists of raw materials (clays, limestone, gypsum) ground and heated to 1400 degrees. It hardens when mixed with water and is used to join bricks and concrete blocks for coatings.
Ceramic Products
Ceramic products are bricks made of ceramic and clay.
Precast Concrete
Precast concrete is concrete molded into a specific shape.
Tile Types
- Ceramic Tiles: Fired clay.
- Concrete Tiles: Formed by cement.
- Slate Tiles: Clay sediments formed at high temperatures.
- Metal Plates: Steel.
