Can someone please explain how the current regularly changes direction after some time in alternating current? I mean if it changes direction, how does it move forward?
Alternating current is a type of electrical current that periodically changes direction, unlike direct current (DC) which only flows in one direction.
Alternating current moves forward by constantly changing direction, with the current flowing first in one direction and then in the opposite direction. This creates a back-and-forth motion that allows the current to travel through a circuit.
The main difference between alternating current and direct current is the direction of flow. Alternating current periodically changes direction, while direct current only flows in one direction. AC is also typically used for long-distance power transmission, while DC is commonly used for small electronic devices.
Alternating current is typically generated by an electrical generator, which uses mechanical energy to rotate a coil of wire within a magnetic field. This creates a flow of electrons, resulting in an alternating current.
Alternating current has several advantages, including the ability to be easily converted to different voltages, making it ideal for long-distance power transmission. It also allows for the use of transformers, which are important for regulating voltage and reducing energy losses. Additionally, AC is more efficient for powering large devices and machinery.
