AC Milliammeter, Model J0414, is suitable for the laboratories of middle schools and polytechnic schools to measure current intensity in the AC circuit.
And as AC continued to grow in popularity, and Edison sensed he might not be able to win the battle if he competed fairly, he started to play dirty, his tactics becoming increasingly underhand.
Tesla's error, if it can be defined as such, is that he was simply ahead of his time in trying to propose alternating current as the better method of energy generation.
I talked about the advantages it has with respect of loss of A.C. power and how it would cool itself down. So there's really no reason to stop the construction.
The people who were giving him money for the company didn't like his ideas about developing technology related to alternating current, so they fired him.
This device that can produce high-voltage, low-current, high-frequency alternating-current electricity was used in the experiments concerning phosphorescence, wireless electricity and X-ray generation.
