440 Volt Current/ why on 440 volt in 3 phase

Image
Today we will read why there is a current of 440 volts in 3 phase electricity. There is no 660 volt, whereas there is 220 volt in single phase, according to this there should be 660 volt in 3 phase. Then it is only 440 volts, let's know further.  Why is there only 440 volt current in 3 phase?   To know about 3 phase current, first we need to know about single phase current flow. AC current always travels in wave form. As you can see in the graph given below.  When current flows, it travels in a wave form. There are 2 points of that wave, postive and negative point. Both these peak points are the points when the voltage is at its full voltage. But there is also a 0 point in between the two points. 0 point is the point when there is no voltage in the phase.   The journey of current from positive to negative goes on very fast. A process happens so fast that 0 point is not detected, where the voltage is 0, just a slight variation of 4-5 volts comes.  It is because of this 0

What is chat gpt?/Advantage And Disadvantage

In today's article, we will know, what is Chat GPT, what is its advantage or disadvantage?  chat gpt Chat GPT is an artificial intelligence chat bot created by a company called Open AI. The full form of Chat GPT is (Chat generated pre-trained transformer). There are many versions of Chat GPT. Which is the latest one. Whose name is Chat GPT-4. Chat GPT works on top of Artificial Intelligence.  The one who can answer all the questions we have. Chat In GPT we can talk with the help of chat. It can give us answers to all the questions which we used to get from Google. Chat GPT can make many of our jobs easier, such as content writing, translator, photography, web designing, or coding.  What is the difference between Chat GPT and Google ? Friends, whenever we search anything in Google's search engine bar. Then Google gives us many answers to the question, but this does not happen at all in Chat GPT. Chat GPT gives only one answer to a question, if you do not like the answer, you can

What is electric current?/ AC and DC current

ELECTRIC CURRENT  Electric current is made up of a group of electrons. Whenever electrons flow in a conductor, that flowing electron is called current or electricity.  types of electric current Current is of two types, AC or DC current   The full name of AC Current is Alternative Current.  The full name of DC current current is Direct Current. difference between ac and dc AC Current   - AC Current is called alternating current. Alternating current is an electric current that continuously changes direction as it flows. AC current flows with Hz. Usually AC current flows at 50 or 60 (hz) hertz. We cannot store AC current in any battery as AC current. (To store it, we have to convert it to DC first)   Image source by Google-https://dam-assets.fluke.com/s3fs-public/6004181-dmm-whatis-frequency-715x360-2.jpg We can increase or decrease the voltage of AC current with the help of transformer. When AC current flows, it flows in a positive or negative cycle. Current flows in both the
