ELECTRIC CURRENT
1. Definition
When electrons move, we say that an electric current is produced. An electric current is formed by moving electrons. Conventional current is in the direction opposite to electron flow. An electric current (I) is the rate of flow of electric charge (Q).
2. Formula
Where:
- I stands electric current (A)
- Q stands for electric charge (C)
- t stands for the time taken (s)
3. Important Figure
Nikola Tesla (1856-1943) was a Serbian-American engineer and physicist who invented the first alternating current (AC) motor and developed AC generation and transmission technology. Though he was famous and respected, he was never able to translate his copious inventions into long-term financial success, unlike his early employer and chief rival, Thomas Edison. In the 1890s Tesla invented electric oscillators, meters, improved lights, and the high-voltage transformer known as the Tesla coil.
4. Uses in Everyday Life
Electric current can be seen from any electrical appliances that you see in everyday life, they're used to power devices and even some of the methods of transportation that we see all around us. To make things operate, electrical energy must be emitted from energy sources such as power plants, to enable an object to consume the power it needs to function.
