Alternating Current
Imagine trying to find the perfect sleeping position and tossing and turning throughout the night, constantly switching sides. This is similar to how alternating current (AC) works, as it continuously changes direction, flowing back and forth just like you change your position in bed. Just as you move from one side to the other to find comfort, AC reverses direction to efficiently transmit energy across power lines, ensuring electricity reaches your home smoothly.
