Direct Current
Direct Current (DC) is a type of electrical current where the flow of electric charge is unidirectional, maintaining a constant polarity over time. It is characterized by a steady voltage and current magnitude, unlike Alternating Current (AC) which periodically reverses direction. DC is fundamental in electronics, batteries, and many low-voltage applications due to its stable and predictable nature.
Developers should understand DC when working with embedded systems, IoT devices, or hardware projects, as it powers microcontrollers, sensors, and digital circuits. Knowledge of DC is essential for designing power supplies, battery management systems, and ensuring compatibility with electronic components that require stable voltage, such as in robotics or consumer electronics.
