How did electricity change American life? It change the nature of business, it made possible new inventions and appliances, and it helped cities and industries grow. Telegraph, telephone, radio; made possible by the invention of electricity. Faster communication and more connectivity.

Electricity has many uses in our day to day life. It is used for lighting rooms, working fans and domestic appliances like using electric stoves, A/C and more. All these provide comfort to people. Modern equipment like computers and robots have also been developed because of electricity.

Society was changed by the discovery of electricity. It led to the invention of labor-saving devices both at work and at home. People’s daily activities were no longer dependent on daylight, a significant impact. The discovery of electricity radically changed productivity in the workplace.

Electricity makes our lives significantly easier. We do not have to walk to a river to get water or wash our clothes and we can cook foods by switching a button.

Electricity allows us to power the technology we use every day. If you plan on trying to live without electricity, you will no longer be able to turn on the central heating in your home, use the toilet, preserve food in your fridge/freezer or have clean running water.

Electricity is an essential part of modern life and important to the U.S. economy. People use electricity for lighting, heating, cooling, and refrigeration and for operating appliances, computers, electronics, machinery, and public transportation systems.

Why study electricity because electrical energy is transmitted very rapidly (almost at the speed of light); and because there are many physical effects involving electrical energy which make possible conversion into light, sound, motion, force, heat, cooling, and rapid transmission of information.

The electric light bulb has been called the most important invention since man-made fire. The light bulb helped to establish social order after sundown, extended the workday well into the night, and allowed us to navigate and travel safely in the dark. Without the light bulb, there would be no nightlife.

The heat is very important in our daily life in warming the house, cooking, heating the water and drying the washed clothes. The heat has many usages in the industry as making and processing the food and manufacture of the glass, the paper, the textile, ………etc.

Productive uses of thermal energy include but are not limited to: cooking, drying, heating, smoking, baking, water heating, cooling and manufacturing.

Answer: Conduction: Heat transfers into your hands as you hold a hot cup of coffee. Convection: Heat transfers as the barista “steams” cold milk to make hot cocoa. Radiation: Reheating a cold cup of coffee in a microwave oven.

Productive use of thermal energy involves a range of activities, such as cooking, drying, heating, smoking, baking, cooling and manufacturing.

Productive uses of thermal energy include but are not limited to: cooking, drying, heating, smoking, baking, water heating, cooling and manufacturing. New and efficient technologies exist that significantly reduce the amount of biomass needed for fuel.

Prolonged exposure to extreme heat can cause heat exhaustion, heat cramps, heat stroke, and death, as well as exacerbate preexisting chronic conditions, such as various respiratory, cerebral, and cardiovascular diseases.

The biggest example of heat energy in our solar system is the sun itself. The sun radiates heat to warm us up on the planet earth. When the burner of a stovetop is very hot, it is a source of heat energy. Automobile fuels such as gasoline are sources of heat energy, as is the hot engine of a racecar or a school bus.

Here are some examples of everyday objects that use electrical energy.

• Washing machine.
• Dryer.
• Television.
• Cell phone.
• Laptop.
• Air conditioning system.
• Flashlight.
• Heating system.

They include watching television, washing clothes, heating and lighting the home, taking a shower, working from home on your laptop or computer, running appliances and cooking. Residential uses of energy account for almost forty percent of total energy use globally.

In our everyday life, we tell the hotness and coldness of different substances and weather in terms of temperature. We also use temperature to find the severity of the fever. For example, our normal body temperature is 98 ⁰F. This temperature increases when we caught in the fever.
