Can I say that energy transmitted in DC by electrons flow like ants walking align and in AC by electron vibration like water wave ?
Pictorial models of something as complicated as Electricity will just manage to confuse you. There is no short cut to understanding Electricity. One thing I can tell you is that using electrons when you want to describe what goes on in circuits is worse than unnecessary. Going back a few decades, schools taught electricity without introducing electrons (despite the fact that it was know how they are 'involved'; that is night here nor there.) We had no trouble in our electrical learning. Most of the electrical devices that you use were designed without using 'electrons' in the analysis. That goes for generators, radio antennas and motors, to name but three)Nihad Nazmul said:Can I say that energy transmitted in DC by electrons flow like ants walking align and in AC by electron vibration like water wave ?
Drakkith said:In both AC and DC the energy is transferred through the electromagnetic field.
Yes.Drakkith said:Are you talking about what is known as 'conventional current' where current flow is envisioned as positive charges flowing?
Nihad Nazmul said:Maybe I messed up energy and current together. Now I have the conclusion. Glowing a light bulb current has no role and it is done by electromagnetic magnetic field .

AC (alternating current) is a type of electrical current that periodically changes direction, while DC (direct current) flows in only one direction. AC is commonly used in household appliances and power grids, while DC is often used in smaller electronics such as batteries.
In AC circuits, the flow of electric charge changes direction periodically, causing the current to alternate between positive and negative values. In DC circuits, the flow of electric charge remains in one direction, from the positive terminal to the negative terminal.
The frequency of AC current is the number of times the current changes direction in one second, measured in Hertz (Hz). In most countries, the standard frequency for AC power is 50 or 60 Hz.
AC current can be converted to DC current using a device called a rectifier. This device uses diodes to convert the alternating current into a direct current by allowing current to flow in only one direction.
AC has the advantage of being able to travel long distances without significant loss of energy, making it ideal for powering large electrical grids. DC, on the other hand, is more efficient for smaller electronic devices and can be easily converted from AC. However, DC requires more complex circuitry to convert and is not suitable for long-distance transmission.
