I am trying to wrap my head around the concept of alternating current (AC) and how it works. What exactly is AC, and how does it differ from direct current (DC)? Any simple explanations or analogies to make it easier to understand would be helpful.

Alternating current (AC) is a type of electrical current where the flow of electric charge periodically reverses direction. In other words, the electrons move back and forth rather than in a single direction. This back-and-forth movement creates a wave-like pattern when graphed, typically a sine wave.
On the other hand, Direct current (DC), is a type of electrical current where the flow of electric charge is only in one direction. The electrons move steadily in a single direction, creating a straight line when graphed.
Just a takeaway, AC is preferred for power distribution because it can be easily converted to different voltages using transformers. This makes it efficient for transmitting electricity over long distances.
Alternating current is the form in which electric power is delivered to businesses and residences, and it is the form of electrical energy that consumers typically use when they plug kitchen appliances, televisions, fans, and electric lamps into a wall socket.
Direct current (DC) and alternating current (AC) are the two ways that electricity moves. The direction in which electrons flow is the primary distinction between AC and DC. While electrons continuously swap directions in AC, moving ahead and then backward, they flow constantly in one direction in DC.
