Energy, Electricity, and Electronic
Transcript of Energy, Electricity, and Electronic
By: Escuela Vieau School
(Luis Mora and Gerardo De La O) Electricity is divided into three different categories: Georg Ohm created which is called " Ohms Law" Ohm's Law Ohm's Law has three quantities which are: Voltage, Current, and Resistance. In order to find the quantities: Voltage, Current, and Resistance They have formulas to one of those 3 quantities, but in order to find two of the three quantities. Formulas are: Voltage= Current x Resistance.
Current= Voltage/ Resistance
Resistance= Voltage/ Current There are charts that can help find Voltage, Current, and Resistance To Find Voltage To Find Current Wind Turbines To Find Resistance Wind turbines are meant to reproduce energy by not harming our environment.
Wind Turbines have a motor which inside then have smaller components inside the motor such as: Rotor(blades), Generator (a generator that produce 60-cycle AC electricity), Low-speed shaft (rotor turns the Low-speed 30 to 60 rotations per minute), High-speed shaft (drives the generator), Gear box (connect from low-speed shaft to high speed shaft to increase the speed from 10 to 60 rotations to 1200 to 1800 rotations per minute), Brake ( stops turbines manually, electronically, or hydraulically to stop in emergencies), Yaw drive (keeps the rotor on facing towards the wind), Yaw motor (powers the Yaw drive), Controller ( starts the machine from 8 to 16 miles per hour and stops the machine at 65 mph so it won't damage the rotor), Anemometer (measures wind speeds then send message to the controller), Wind vane ( measures wind and communicates with the controller), and the Tower (reaching the highest point to get winds). Renewable resources Renewable and Non-Renewable resources Non-Renewable resources The difference between a Renewable and a Non-Renewable resources is that renewable can be renewed without taking a lot of Earth's time and without harming our world while non-renewable take a lot of years to reproduce. Wind Power
Uranium/ Nuclear Solar Power and Hydro power Solar power is the conversion of sunlight to electricity by using Photovoltaic (PV). Sunlight beams down on Solar panels, then electrons knock each other from each atom to, then make electricity.
United States on use 8% of renewable resources. Approximately 2% of it use in Solar power. Hydro-power is the conversion of water waves into electricity. The most common type of hydro-electric power uses a dam or river. The most important part of the hydro-power system is the Pelton wheel. Lester Allan Pelton was the creator of the Pelton wheel. He created it in 1880. The first Hydro-power plant was in Appleton, Wisconsin. Approximately 2% of United States renewable resources of it use in Hydro-power. Environmental Benefits: Being the renewable source of energy, geothermal energy has helped in reducing global warming and pollution. Moreover, Geothermal systems does not create any pollution as it releases some gases from deep within the earth which are not very harmful to the environment. High installation costs – because it takes power plants to get geothermal energy, the costs of the plants is very high.The water is heated by Molten rock. The depths can go up to 9,800 feet. The Wells are similar for those that can produce crude oil and nature gas are drilled to recover the water. When it’s captured the stream and the hot water there separated. Now the steam is cleaned and sent the Power Plant. When the separate water returns back to the process. To use reuse and make more geothermal energy. Geothermal is from the Greeks. Geo means earth and thermal means heat. Geothermal has been used more than over 20 countries such as the United States, Italy, France, Lithuania, New Zealand, Mexico, Nicaragua, Costa Rica, Russia, the Philippines, Indonesia, the People's Republic of China and Japan.
Biomass is energy, organic matter, ever plant matter that can be converted to fuel and is therefore regarded as a potential energy source. Like some examples of matter can be made into biomass energy would be like wood, waste, alcoholic fuels, crops, and even landfill gases. California produces 60 million dry bones tons of biomass. If 60 million tons are created, then approximately 2,000 megawatts are created. Geothermal and Biomass Non-renewable These are non-renewable and will run out a some point in Earth's time.
Coal- is a very harmful way to get energy. First of all it pollutes the air. When you burn the coal it creates Co2 emissions to pollute air.
Natural Gas- is very high flammable and needs to be in very high managed or it will explode.
Crude Oil- is use for gasoline they process it, then to create gasoline. Gasoline is very flammable, and when cars use it creates lots of Co2 emissions.
Uranium/ Nuclear- Uranium/ Nuclear is clean, but if the factory were to get damage such: explosion, etc. it would cause radiation. DC and AC electricity DC AC DC means direct current. DC is mostly use in electronics that have a circuit board inside. Every electronically device requires DC, but the have a inverter from AC to create DC. If you were to be dealing between a motor DC is fairly more simpler and it keeps in a constant speed. AC means Alternative current. AC is use in long-range electronic devices. In a AC motor it goes from high to low and it don't have a constant speed, also AC motors are more difficult to build than DC motors. Circuits A Circuit a closed path with a electrical source to power the device with a positive and negative flow. In order for the circuit to flow atoms jump through each electron knocking another atom out and continue traveling to power what it's needed to power. In a circuit you can place resistors so you can block so electrons from continuing the flow. Resistors have different values. They higher the resistance of the resistors it limits the flow of the electrons. In a circuit there will always be Volts, Amps, and resistance ( if you want to dim down brightness). In order to find resistance you find the bands in the resistors and each color band have a different value, and the gold band always on your right. In order to find resistance you get positive and negative wires and connect to negative to negative and positive to positive, and in your multimeter you change it to Ohm's to then find your resistance. Snap Circuits Garage Door Chicken Coop Burglar Alarm Traffic Light Electronics Phones, video game systems, etc. have a special board called a electronic board. Electronics have a special board because when you use your Solder Iron the melted solder wire has to get stuck onto the board. On the board it has a silver board for the solder wire can get stuck on their when you burn the wire. The Solder Iron is very hot, and if it is used in a wrong way it can give someone a third degree burn. If you are not careful you can burn the electronic board and can stop flow through the board. Also if to much solder wire is applied on the silver part and spreads to the board it can stop circuit and your design won't work. When you are placing the objects onto the board pieces have a special way to insert them such as: LED's ( they have a flat part), NPN transistors (flat side and to go with flat), and Capacitors ( negative goes with negative and positive with positive). Energy comes in different forms such as: heat/thermal, light/radiant, motion/kinetic, electrical, chemical, nuclear, gravitational and even mechanical, those are some forms that energy can take. Energy can be moved or changed from one object or form to another. Energy cannot be created or destroyed. object What is Energy? Wind Turbines Wind Turbine examples Energy from the past is still used today. Energy cannot be destroyed or created, but it can be stored in batteries. Different batteries hold up different amounts of batteries. AAA hold up to 1.5 volts, AA also hold up 1.5 volts, ect. Batteries also have a negative and a positive side on them and if you connect wires to the positive and negative sides it will create a circuit. While circuit is create a chemical reaction occurs, but until electrons flow. Batteries can store for a long time because a chemical reaction hasn't occur if a chemical reaction has occur it will have a less battery life. . Stored Energy & Batteries Alexander Volta was the first person to create the battery. Electricity travels easily through a circuit, but electricity moves more easily then others. Metal is a good conductor of electricity. That is why wires are made of metal. Metal allows electrons to flow in each atom. Examples of conductors: Copper, Gold, and Aluminum. Conductors and Insulators Some materials don't let electricity flow through them, and they are called Insulators. Plastic is a good insulator that is why wires are mostly wrapped in plastic. The plastic keeps the electricity from flowing into people or objects that touch the wires.
