AC vs. DC: The Fundamentals of Power
Electrical Engineering revolves around these two types of current. While they both carry energy, their behavior and applications are worlds apart.
🔹 AC (Alternating Current)
Flow: Reverses direction periodically (Sinusoidal wave).
Transmission: Efficient for long distances via Transformers.
Frequency: Usually 50Hz or 60Hz depending on the country.
Examples: Wall outlets, Refrigerators, Industrial Motors.
🔹 DC (Direct Current)
Flow: Constant flow in a single direction (Straight line).
Storage: Can be stored in batteries and capacitors.
Frequency: Always Zero (0).
Examples: Smartphones, EVs (Electric Vehicles), Solar Panels.
