If you contact a live wire while being grounded, you will receive a shock. When a circuit, electrical component, or piece of equipment is turned on, a potential shock hazard exists. Typically, black and red wires are powered, whereas white wires are neutral. However something can be plugged into any white socket so if you are not sure what the other wires do, just stick to the black ones.
You should also know that electricity is not the same as voltage. Voltage is the force that drives electrons through a conductor such as a copper wire. Electricity is the flow of electrons through a conductor such as a copper wire. The two are related but not identical. For example, lightning is electricity but not all forms of electricity are lightening; high-voltage power lines carry electricity but they are not lightening rods.
Electricity is only dangerous when it flows through a person or object. If you come in contact with a live wire but do not get shocked, there is no problem. The current will pass through your body without incident because you are not a conductor of electricity. Only things that conduct electricity can be damaged by touching a live wire (such as a metal fence or tree).
People often ask about touching a metal object like a car bumper. This is fine as long as you don't go between the front and back cars or climb under the vehicle.
If you contact two wires with different voltages at the same time, you will experience a shock. Always turn off the power before working on any wiring in an area where people can sleep-this is very important!
The electricity from a power line is called "voltage", and the voltage of a power source can be either high or low. Low-voltage sources include household current (120 volts) and most industrial circuits (240 volts). High-voltage sources include those found in laboratories and factories (240 volts) and those for electric vehicles (120 volts). The term "ground" means a safe place to touch or connect something; it's a reference point for electricity. A "grounded" conductor connects one side of the system to the ground.
In order to protect people from electrical hazards, the law requires that all exposed parts of electrical systems be guarded by conductors who's potential equals that of the main body grid. These conductors are called "shunts". Where there are no shunt conductors, people are left to their own devices when it comes to electrical safety. In other words, they're on their own protection against electrical hazards.
You will be shocked by electricity. Always use caution to avoid contacting live wiring.
The best way to avoid contact with live wiring is to always follow these steps:
1. Check the power switch in your home to make sure it's not locked into the "on" position. If it is, turn it off immediately.
2. Look for any loose or broken wiring before you start working on your house's electrical system. Make sure you don't have any open circuits or shorts that could cause voltage to reach parts of the house where it shouldn't. If you find any problems, have them fixed by a professional before you work further on your own.
3. Don't stick anything into an outlet or try to fix something by yourself if you aren't sure what you're doing. Call an expert who can help you prevent damage from happening again.
If you do contact live wiring, stay away from all power sources until notified by an electrician. Contacting live wiring can result in serious injury or death.
Contacting live wiring may also violate local housing code provisions.
If you contact the live wire on the ground, you will receive a shock. If you contact a live wire with only one hand, the current route is incomplete and no shock is felt. However, if you contact both hands on a live wire, then you have completed the circuit and received a shock.
This is because your body is a complete circuit, and must be closed in order for a current to flow. Since your other hand is not connected to anything, it cannot create a path for the current to follow, and so does not receive any power. This means that you can touch a live wire without being harmed as long as you do so in a way that prevents you from completing the circuit.
However, if you were to put your finger on the live wire and use it to pull yourself closer to it (or even touch it again after initially not doing so), then this would complete the circuit and you would now be in danger.
The same thing would happen if there was another person present who had their hand on the live wire - they would also get shocked if they did not take their hand off immediately or if they did not tell you not to touch it.
It is important to remember that contact with a live wire should be avoided entirely unless you are trained to work with electricity.
