The primary difference between alternating current (AC) and direct current (DC) lies in the direction in which the electric charge flows.
Direct Current (DC):
In direct current, the electric charge flows in a single, consistent direction.
Example:
Batteries are a common source of DC. In a battery-powered device, such as a flashlight, the electricity flows from the battery’s positive terminal, through the device, and back to the battery’s negative terminal in a single, unidirectional flow.
Alternating Current (AC):
In alternating current, the direction of the electric charge periodically reverses. This means the charge flows back and forth, changing direction multiple times per second.
Example:
Household electrical outlets supply AC. For instance, when you plug in and turn on a lamp, the electrical current alternates, typically at 50 or 60 times per second (50 Hz or 60 Hz, depending on the country), allowing the lamp to light up.
