Electronics primarily use DC because it provides a stable current flow necessary for digital circuits, where the presence of current represents a "1" and its absence a "0." AC, which fluctuates and can drop to zero multiple times per second, complicates this binary representation and can interfere with time-varying signals. While AC is prevalent in power generation and heavy machinery, most electronic devices rely on DC due to its compatibility with components like transistors and capacitors. Additionally, DC is favored in battery-operated devices, making it more practical for modern electronics. Overall, the preference for DC in electronics stems from its reliability and efficiency in processing signals.
