Low voltage can refer to both DC (Direct Current) and AC (Alternating Current), depending on the context.
- **Low Voltage DC**: This refers to a direct current system where the voltage is relatively low. For example, typical low-voltage DC applications are 5V, 12V, or 24V systems, often found in devices like LED lights, battery-operated electronics, and small motors.
- **Low Voltage AC**: This refers to alternating current systems with lower voltage levels. For example, household power supply in many countries (like 110V or 230V) is AC, but low voltage AC could be something like 24V AC, used in some control circuits or small transformers.
So, **low voltage** can apply to either DC or AC depending on the specific application. But when people mention low voltage in casual conversations, they are often talking about DC, like in power supplies or electronics.
