AC vs DC: Debunking Myths and Examining Modern Usage

Nikola Tesla significantly contributed to the development of alternating current (AC) technology, which has been the dominant power distribution system for over a century due to its efficiency in long-distance transmission. The debate surrounding Tesla's legacy often contrasts his achievements with those of Thomas Edison, with some viewing Tesla as over-romanticized and others as a pivotal figure in electronics. In modern society, AC remains the preferred choice for power distribution, while direct current (DC) is increasingly utilized for long-distance and international connections due to lower losses and lack of synchronism requirements. The discussion acknowledges that while Tesla's innovations were valuable, they have been exaggerated over time, likening him to other notable figures in technology rather than a revolutionary scientist. Overall, AC is favored in power distribution, but DC plays a crucial role in specific applications today.

Hello, All!

This is a thread that should address my questions and evolve into a general discussion on AC and DC for the purpose of interest.

My first question is: What did Nikola Tesla add to the field of electronics and AC? I've read all over the web two conflicting ideas 1) Tesla is God, Edison is the Devil and 2) Tesla added little to an already rich field. To what degree, if any, are either of these two ideas correct?

My second question is: How are AC and DC used in today's modern society and was there a 'winner' to the current wars?

While my knowledge is limited in the field, which shows through the way in which I am asking the questions, answers in full detail would be appreciated.

Of course there was a 'winner' for Power distribution. AC has been the system of choice for a hundred years, for good reason. However, for really long distance and international links, DC is used as the losses are less and you don't need synchronism between the systems. It's at least 40:15 in AC's favour.

Tesla was, to my mind, judged correctly by his peers and has been over romanticised by the public later on. What he did was very useful but what he 'talked about doing' has been picked up by his 'followers' and now and is now up amongst all the other Myths of our time, like the Faked Moon landings and the area 51 thing. The Tesla Transformer is such a sexy beast to see that he won the hearts of millions of punters. Good luck to him but he was more like a Clive Sinclair or Alan Sugar, imo, than a Paul Dirac.
 

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...

Thread 'Question about bonding ground and neutral'

I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...
