Where is alternating current used?
Can you explain where alternating current, or AC, is commonly utilized? I'm particularly interested in understanding the various industries and applications that rely on this form of electrical current for their daily operations. Are there any specific advantages or benefits that AC offers over direct current, or DC, in these contexts? Additionally, I'd appreciate it if you could highlight some real-world examples to illustrate the prevalence and significance of AC in modern society.
Why is alternating current better?
Could you elaborate on why alternating current is considered superior to direct current in various applications? What are the key advantages that AC offers over DC, particularly in terms of efficiency, transmission over long distances, and compatibility with modern electrical systems? Additionally, how does the sinusoidal waveform of AC contribute to its effectiveness, and what challenges does it pose in comparison to DC?
