Introduction to negative and positive wires:
Let us first discuss about electricity, which can pass through the wires. There are two types of current, one is called the alternating current, which is used, in electrical mains and the other is called direct current, which is used, in the car’s light and in the radio. Direct current is obtained by the battery. Let us discuss the wires, which carry the electric current.
Types of Negative and positive wires
Generally, there are three types of the wires:
Positive wire,
Negative wire and
Ground wire
In case of direct current, the positive wire is the wire, which carries 120 V. Negative wire is the wire, which has about 0 V. Ground wire is actually connected to the ground. Negative wires should be at zero potential or close to zero potential. It is the central point between the two phases of the electrical service coming to your house from the transformer on the electrical pole. Positive wire is the wire, which supplies the electric current to the electrical appliance. It is supplied to the devices in your home through a set of circuit breakers or fuses in older homes. It is wired directly to the outlets, and goes to the permanently installed lighting through the permanent wall switches. There is a standard colors in house wiring are: positive wire is of red color, negative wire is of black in color and the ground wire is of green in color.
Conclusion for negative and positive wires
Some of the devices in our daily life have only two flat prongs, and some have the third, round grounding prong. The two-prong devices are typically low current, low-power devices like lamps, bulbs, clock radios, can openers and the like. The third prong generally appears on higher-powered devices: washing machines, vacuum cleaners, televisions, computers, leaf blowers, drills, etc. This is usually done for safety reasons. This is also, why miswired outlets are dangerous: if the neutral and hot are reversed, the appliance will work just the same. However, if the appliance fails, the 'stray' energy remains under the 'top' insulating layer (next to the user), Not in the bottom one, putting the user at much greater risk. In older tools with metal cases, the user would actually get electric shocks in this event.
