440 Volt Current/ why on 440 volt in 3 phase

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 ampere?/Voltage/Resistance/

In today's modern times, electricity has a huge contribution. If we know about electricity then we would get to see Voltage, Ampere, Resistance, and Watt, so today we will know about all these.  Ampere Ampere is the amount of electrons flowing in a conductor. It is the amount of measurement of electrons flowing in a conductor. In 1 ampere, 6.24*10^18 electrons flow per second.  Can we control Ampere with the help of transformer? We cannot increase or decrease Ampere with the help of transformer, but there are some electronic devices, which can increase or decrease Ampere. Ampere always flows with the help of Voltage. The symbol of Ampere is like this.  what is voltage Voltage is an electrical force that drives the flow of electrons in a conductor. Meaning in simple language, you can understand that Voltage is such a power, which pushes the electrons present in the conductor. Due to which current flows in the conductor. Electron never flows by itself in the conductor. Voltage is req
