What gauge wire to use for 12 volts?
Maximum current - amps - through a 12V circuit - related to size (AWG) and length of wire

A DC connector (or DC plug, for one common type of connector) is an electrical connector for supplying direct current (DC) power. Compared to domestic AC power plugs and sockets, DC connectors have many more standard types that are not interchangeable.
- DC means "direct current", more accurately non alternating current. A DC charger is used to charge Battery of a DC driven electronic accessories like laptop, mobile, tablet, etc.
- AC power plugs and sockets are devices that allow electrically operated equipment to be connected to the primary alternating current (AC) power supply in a building. Electrical plugs and sockets differ in voltage and current rating, shape, size and type of connectors.
- Power Connector. A common weak spot on most laptops is the DC power jack. Any sideways pulling of the DC power cord while attached to the laptop will usually dislodge at least one of these pins, breaking the solder around it.
Stranded wire is good for both. However the single strand wire works better with DC and is rarely used with AC due to the skin effect of AC current. Stranded wires do not get affected by this phenomenon because of their high surface area and low ccross-sectional area.
- Due to the wires having electrical resistance, which means that they resist the motion of electrons, the electrons bump into atoms on the outside of the wire, and some of their kinetic energy is given to the atoms as thermal energy. This thermal energy causes the wire to heat up.
- With its exceptional current carrying capacity, copper is more efficient than any other electrical conductor Because of its superior conductivity, annealed copper is the international standard to which all other electrical conductors are compared . Another advantage is that copper oxide also conducts electricity.

Wire is a single electrical conductor, whereas a cable is a group of wires swathed in sheathing. The term cable originally referred to a nautical line of multiple ropes used to anchor ships, and in an electrical context, cables (like wires) are used to carry electrical currents.
- When was wire invented and when did its use for fencing become general? I remember reading that the invention of barbed wire changed the face of the American West. ORDINARY wire was invented about 2,000 years ago. In 1873 Joseph Glidden, an American farmer, invented barbed wire similar to that in use today.
- The benefits of using copper conducting wire were known, but the technology was not available to make a enameled copper wire strong enough for an overhead wire. Then in 1877 Thomas Doolittle developed the process for hard drawn copper wire in the Naugatuck Valley of Connecticut.
- Copper is one of the basic known elements, noted as Cu on the periodic table and has an atomic number of 29. Although native copper is somewhat rare, large amounts are found by the Great Lakes and was mined by ancient American cultures.
