Light trivia: 10 interesting facts about electric current
It is hard to imagine life without electricity. Electricity provides almost all the comforts of life, making itself a basic necessity. However, even if people use electricity in their homes, offices or industries every day, little do they know much about it.
Well, did you know coal is the biggest source of energy for producing electricity? Or the first electric power station was set up in New York in 1882 by Thomas Edison? To know more such interesting facts about electricity, keep on reading:
Check out Interesting facts about electric current:
- Electrical energy travels at the speed of light: Electricity travels very fast, over 186,000 miles per second (300,000 km/second). Light from a stationary source travels at the same speed.
- World's largest lightbulb is located in Edison, New Jersey: The world’s largest light bulb is located in Edison, New Jersey. The 14-feet tall and eight-ton lightbulb sits on the top of the Thomas Edison Memorial Tower, which is illuminated at night.
- Electrical energy travels in closed loops: Electrical energy or current travels in closed loops -- circuits. Circuits should not contain breaks and must be closed for the electrons to move. A circuit mostly consists of an energy source, a switch, load and wires.
- Electricity was discovered as early as 600 BC: You would be surprised to know that electricity was first discovered around 600 BC by the Ancient Greeks. A Greek philosopher Thales of Miletus described that rubbing fur against substances such as tree amber can create static electricity.
- LED light bulbs use 80% less energy: The latest form of lighting source, LEDs use 80% less energy than the traditional incandescent bulbs. The conventional light bulbs use only about 10-20 per cent of electrical energy to power the bulb, while wasting the remaining percentage through heat. However, LEDs use almost all of the electrical energy to power the light bulb and emit little or no heat, making them safer to use.
- Spark of static electricity measures up to 3,000 volts: A spark of static electrical energy can measure up to 3,000 volts. While one single bolt of lightning can measure up to three million volts and will last less than a second.
- Electricity travels through several transmission lines, facilities and wires to reach your homes: Electrical current travels from generation facilities to switchyard, then to transmission lines to a substation to a distribution line and finally from a transformer it reaches your house.
- Electric eels can generate shocks of over 500 volts: Electric eels can produce electrical shocks of up to 600 volts to keep their predators away. This also helps them to stun their prey.
- Common domestic items powered by electricity: Have you ever wondered which were the first common domestic items that were powered by electricity? They were fans, kettles, sewing machines and toasters.
- First successful electric car was invented in 1891: The first successful electric car was by an American inventor William Morrison in 1891. It was a self-powered, four-wheeled electric carriage.
