The modern society relies heavily on the versatility and the convenience of electricity. It helps light our houses, lets us watch television, powers our computer and microwave, run industries and so much more.
Electricity is a type of energy that flows from one place to another. When electricity gathers only in one place it is called as static electricity. But the electricity that moves or flows from one place to another is known as electric current. The current is simply the flow of electric charge. Some interesting and amazing facts about electric current are provided below.
- Electricity travels at the speed of light, i.e. more than 186 thousand miles per second.
- Electricity was never invented, it was discovered.
- The muscle cells in the human heart are contracted by electricity that runs throughout the body. It plays a very important role in the way the human heart functions.
- Thomas Edison did not invent the first light bulb. But Edison invented the one that stayed lit for a few seconds.
