12V DC (Direct Current) power refers to an electrical power supply that provides a constant voltage of 12 volts in one direction (direct current) rather than alternating between positive and negative, like AC (alternating current).
Here’s a breakdown of the term:
Common Uses of 12V DC:
12V DC is considered safe and easy to work with, which is why it’s common in both household and automotive applications.
Here’s a breakdown of the term:
- 12V: This indicates the amount of electrical potential or "pressure" provided by the power supply. In this case, it's 12 volts. The voltage is what drives the current (the flow of electrical charge) through a circuit.
- DC (Direct Current): This means that the electric charge flows in a single direction, unlike AC (Alternating Current), where the charge periodically changes direction. In DC, the current always flows from the negative terminal to the positive terminal of a power source, like a battery or DC power supply.
Common Uses of 12V DC:
- Batteries: Many devices, such as cars, use 12V DC batteries.
- LED lighting: Many LED lights run on 12V DC power.
- Solar Power Systems: Solar panels often charge 12V DC batteries for energy storage.
- Low-power devices: Gadgets like portable fans, power adapters for electronics, and some toys use 12V DC.
12V DC is considered safe and easy to work with, which is why it’s common in both household and automotive applications.
