Why is AC current used in homes?
Why is AC current used in homes? Why we use AC voltage in our homes despite DC voltage gaining traction. Simply put, AC voltage is capable of converting voltage levels with just a transformer, making it far easier to transport across great distance than DC, whose conversion requires more complex electronic circuitry. How do I […]
