Answer:
Electronic circuits primarily use DC (Direct Current) instead of AC (Alternating Current) because DC provides a stable and consistent voltage, making it easier to control and regulate electronic components.
Reasoning:
- Stability: DC maintains a constant voltage, crucial for the stability of electronic components.
- Simplicity: DC circuits are simpler to design and troubleshoot compared to AC circuits.
- Component Compatibility: Many electronic components, such as transistors and microchips, operate more efficiently with DC.
- Power Supply: Most electronic devices, like batteries and power adapters, provide DC power.
- Signal Processing: DC is essential for tasks like analog signal processing and digital logic operations.
