Fill in the blanks (вставьте пропущенное слово по смыслу) 1. A generator is an electric machine, which a) mechanical energy into electrical energy.
2. A direct-current generator consists of b) .
3. The dynamo was invented by c) in 1831.
4. The d.c. generator is used for various purposes such as d) .
Explanation: A generator is a device that converts mechanical energy into electrical energy. When the generator is running, it utilizes the principle of electromagnetic induction to convert the rotational mechanical energy into electrical energy. This electrical energy can then be used to power various devices.
2. "essential parts" - A direct-current generator consists of essential parts.
Explanation: A direct-current (DC) generator typically consists of several essential parts. These parts include the armature (also known as the rotor), which is the rotating component that produces the electrical output, the stator, which is the stationary part containing the field windings, and the commutator, which helps to convert the alternating current generated by the armature into direct current.
3. "Michael Faraday" - The dynamo was invented by Michael Faraday in 1831.
Explanation: Michael Faraday, an English scientist, is credited with the invention of the dynamo in 1831. Faraday's discovery of electromagnetic induction laid the foundation for the development of electrical generators. His experiments and inventions revolutionized the field of electromagnetism and paved the way for many modern electrical devices.
4. "power generation" - The DC generator is used for various purposes such as power generation.
Explanation: DC generators are commonly used for power generation in various applications. They can be found in power plants, where they convert mechanical energy from turbines into electrical energy. DC generators are also used in vehicles, such as cars, buses, and motorcycles, to charge the battery and power the electrical systems. Additionally, DC generators are utilized in portable devices like hand-cranked flashlights or emergency power sources.
