#### What devices and machines using electricity have become a part of our everyday life? Electricity has become an integral part of our everyday life, powering various devices and machines that we rely on. Some of the devices and machines that have become a part of our everyday life and use electricity include: 1. **Smartphones and Tablets**: These portable devices have become essential for communication, entertainment, and accessing information. They rely on electricity to function and recharge. 2. **Computers and Laptops**: Computers and laptops are widely used for work, education, and entertainment. They require electricity to operate and power their components. 3. **Televisions**: Televisions have evolved from bulky CRT models to sleek LED and OLED screens. They rely on electricity to display images and sound. 4. **Refrigerators and Freezers**: These appliances are essential for preserving food and beverages. They use electricity to maintain a cool temperature and prevent spoilage. 5. **Washing Machines and Dryers**: These appliances automate the process of cleaning and drying clothes. They rely on electricity to power their motors and heating elements. 6. **Air Conditioners and Heaters**: Air conditioners cool the air in hot weather, while heaters warm the air in cold weather. They use electricity to regulate temperature. 7. **Microwaves and Ovens**: Microwaves and ovens are used for cooking and heating food. They rely on electricity to generate heat and cook food. 8. **Electric Vehicles**: Electric vehicles are becoming increasingly popular as a more sustainable mode of transportation. They use electricity to power their motors and rechargeable batteries. These are just a few examples of devices and machines that have become a part of our everyday life and rely on electricity. #### What devices and machines have made electricity most widely used in all fields of science, technology, and industry? Electricity has become the most widely used form of energy in all fields of science, technology, and industry. Several devices and machines have contributed to this widespread use of electricity, including: 1. **Generators**: Generators are machines that convert mechanical energy into electrical energy. They play a crucial role in generating electricity on a large scale, powering industries, homes, and infrastructure. 2. **Transformers**: Transformers are devices used to increase or decrease the voltage of an electric power supply. They are essential for transmitting electricity efficiently over long distances and distributing it to different locations. 3. **Dynamo**: A dynamo is a machine that generates electricity using electromagnetic induction. It has been widely used in various applications, including early power generation and electric motors. 4. **Batteries**: Batteries store electrical energy and provide a portable source of power. They have revolutionized the use of electricity in portable devices, such as smartphones, laptops, and electric vehicles. These devices and machines have played a significant role in making electricity the most widely used form of energy in science, technology, and industry. #### What devices and machines are based on the specific properties of electricity? Several devices and machines are based on the specific properties of electricity. These properties include conductivity, magnetism, and the ability to produce heat and light. Some examples of devices and machines based on these properties are: 1. **Radar**: Radar is a device that uses radio waves to detect the presence, direction, distance, and speed of objects. It relies on the properties of electricity, such as electromagnetic waves and their reflection, to provide information about position and movement. 2. **Appliances**: Various household appliances, such as food mixers, toasters, and dishwashers, are based on the specific properties of electricity. They utilize electrical energy to perform specific tasks, such as mixing, toasting, and cleaning. In summary, radar and household appliances are examples of devices and machines that are based on the specific properties of electricity. #### Fill in the blanks with the following words: radar, battery, generator, appliances, dynamo, transformer. 1. A **generator** is a machine that generates electricity, steam, gas, etc. 2. A device giving information about position, movement, etc. is named **radar**. 3. A machine for changing water and steam power into electrical energy is known as a **dynamo**. 4. Food mixers, toasters, modern dishwashers, and a number of the most recent home devices are household **appliances**. 5. An apparatus to increase or decrease the voltage of an electric power supply — **transformer** — was invented at the end of the 19th century. 6. It is known that a portable cell for supplying electricity is called a **battery**. I hope this helps! Let me know if you have any more questions.
