A few of the important technical blog posts are Neutral wire voltage, Power factor, Open circuit CT transformer, why 30 mA RCCB breaker, Motor type in train engine, AFCI AFDD breaker, and AC DC supply danger to humans.
In this article, we will discuss the application of the autotransformer. As an autotransformer is small in size, cost, and weight, and also can provide variable voltage.
So both the step type and variac type of the autotransformer find use in home, industry, and high voltage labs.

I will explain the difference between neutral wire and earth in the AC supply in this technical article. A total of 17 differences between neutral and earth are discussed in this article.
The three-phase AC supply consists of 4 wires. R phase, Y phase, B phase wire, and a neutral wire. In addition to that, we have earth wire also. The neutral wire and earth wire of the AC supply have totally different purpose.
