The day stage of the process involves channelling the river water into a high-level reservoir backed up by a dam. There is an intake area leading to the power station that opens during the day and closes at night. Water flows during the day to generate electricity through...
The diagram is an illustration of how a hydroelectrical power plant works togenerateelectricity. 开始注意:制作/制造工序类型的流程图的词汇核心在于(但不限于)动词。 The damobstructstheinfluxof water from the river andcreatesa reservoirat a great height. At the bottom of the dam is an entry point...
Static electricity or ESDis an electrical charge at rest. This is created by an imbalance of electrons that stay on a specific surface, or in the environmental air. The imbalance of electrons is caused by absence or surplus of electrons. This creates an electrical field that is capable of in...
The generator, as you might have guessed, generates the electricity. The basic process of generating electricity in this manner is to rotate a series of magnets inside coils of wire. This process moves electrons, which produces electrical current. The Hoover Dam has a total of 17 generators, ...
At this moment, we have made the choice as a society to save the money and live with the risk of losing power. Until we make a different choice, then, it makes sense to be prepared for those times when electricity is not an option. Geomagnetic Storm A geomagnetic storm is a strong di...
15. What is Mia likely to do right after she returns home? A. Watch TV. B. Send a message. C. Roast a chicken. 16. How did Bob get the sweater? A. His mother made it for him. B. His brother gave it to him...
How much electricity is in the human body? Scientists agree that the human body, at rest, can produce around 100 watts of power on average. This is enough electricity to power up a light bulb. Some humans have the ability to output over 2,000 watts of power, for instance if sprinting....
As the copper coils spin within the magnets, electricity is produced. Power lines connected to the generator carry electricity from the power plant to homes and businesses. Westinghouse's Niagara Falls plant was able to transport electricity more than 200 miles (322 kilometers). Not all power ...
A transformer is based on a very simple fact about electricity: when a fluctuating electric current flows through a wire, it generates a magnetic field (an invisible pattern of magnetism) or "magnetic flux" all around it. The strength of the magnetism (which has the rather technical name of...
A hydropower facility consists of a plant for electricity production and a water reservoir formed by a dam in a river. The dam has gates that can open or close depending on how much water is needed to produce a certain amount of electricity. The electricity is transported through ...
