the principle of ac current is that it has
1.it has bipolar polarity
2.its avg power and avg energy can be calculated
direct current alternating current
An alternating current (AC) is a type of electric current that changes direction periodically. It moves back and forth in a cyclic manner, typically in a sinusoidal waveform. AC is commonly used in household power supply systems and many electronic devices.
A frequency converter is a power electronic device. It transforms Direct current to Alternating current of desired frequency and magnitude.
Alternating current (AC) is generated by rotating a coil of wire within a magnetic field, which induces an alternating voltage in the coil. This process is known as electromagnetic induction and is the principle behind how AC electricity is produced in power plants.

The basic principle of current transformer is same as that of the power transformer. Like the power transformer current transformer also contains a primary and a secondary winding. Whenever an alternating current flows through the primary winding alternating magnetic flux is produced, which then induces alternating current in the secondary winding. In case of current transformers the load impedance or "burden" is very small. Therefore the current transformer operates under short circuit conditions. Also the current in the secondary winding does not depend load impedance but depends on the current flowing in the primary winding.
"What is alternating current machine?"
every electronic circuit works on the principle of direct current .hence from negative to positive.
It seems there is a misconception. Alternating current (AC) constantly changes direction, while direct current (DC) flows in one direction. Most electronic devices, including computers, typically require direct current for operation, but they convert AC from the mains power supply using a power adapter or internal power supply unit.
The source is the RF current in the transmitting antenna.
The symbol for alternating current is: ~
Vac usually stands for voltage alternating current. It represents the voltage of an alternating current electrical system.
