The concepts of **AC (Alternating Current)** and **DC (Direct Current)** were developed by different inventors over time.
### **Direct Current (DC)**:
- **Thomas Edison** is most famously associated with **DC**. He developed and promoted the use of direct current for electrical power distribution in the late 19th century.
- In DC, the electrical current flows in one direction only, making it simple but less efficient for long-distance power transmission.
### **Alternating Current (AC)**:
- **Nikola Tesla** is the person most closely linked to **AC**. He developed the technology for generating and distributing alternating current efficiently, which allowed for long-distance power transmission.
- **George Westinghouse**, an American businessman, helped commercialize Tesla’s AC system, and together they played a huge role in the "War of Currents" against Edison’s DC system.
### The "War of Currents":
- **Edison** tried to promote DC, while **Tesla** and **Westinghouse** promoted AC, which turned out to be much more effective for transmitting power over long distances.
- Ultimately, **AC** became the standard for electrical power distribution around the world because it can be easily transformed to different voltages, making it safer and more efficient for long-distance travel.
So, while Edison is credited with developing **DC** and Tesla with **AC**, it’s important to note that both forms of electricity have their specific uses in different applications today!
