electric shock is a physiological symptom caused by an electric current flowing though the body. the current causes heating and, at higher levels, burns, and eventually death.
The bare wire has an electric potential of some substantial voltage above ground. This potential causes a current to flow through your body to ground. if some other part of your body is not connected to ground, no current will flow. The current causes burning in your blood stream, your nervous system, and in you tissue.
the current that flows through your body needs to be above about 10mA for you to perceive it as a shock. The voltage required to produce this current, by ohms law, depends upon the resistance between the point of contact and ground.

In an electromagnet why is it a good idea to use insulated wire?
Because bare wire would short out as the wires are touching each other.
What is the third prong in plug for?
On a British plug it is the earth pin connected to the earth wire. This is safety feature to stop electric shock
Why do you repel when you get an electric shock?
You naturally jerk away from an electric shock, like a static shock you can produce when the humidity is low in your house. Taking a shock from a higher power source affects the muscle tissue involved because the nerves all through the tissue conduct the electricity and trigger muscle contraction. If the current is high enough, it can burn the tissue. If you grab a wire that is live with a DC source, you may be able to force your muscles to let go of the wire. If the wire you grab is driven by an AC source, your muscles will contract, relax, contract, and relax at the frequency of the source. You may not be able to let go of the wire. This is why you NEVER get near downed power lines, even if they look dead. ALWAYS treat electrical circuits as if they are live.
Can electric fields be harmful?
Before lightening strikes, there has to be an electric field. If you grab a live wire, the voltage of the wire creates an electric field in you which drives the current that kills you.
How the charge on a wire changes when an electric current flows in the wire?
2 plus 2
Will you get shock if you touch a bare wire connected to an outlet?
If your getting a shock by touching a wall than you have a bare wire touching the wall, call an electrition
Why does a bare electricity wire with current flowing though it give an electric shock and what happens if the body wet?
Electric current flows on the outside of the wire, not inside the wire. An insulated wire covers that surface where the current is flowing so that you are not touching the wire which actually carries the charge. The body has a pretty large eletrical resistance. If wet, the salts from sweating, form a more conductive surface.
Why do my rear lights not work?
Could have a short in your wire, a bare wire touching bare metal could cause it to ground out.
Why is insulation required in case of metal wire?
Because of the risk of electric shock to people touching it ! It also guards against two wires touching each other - causing a short circuit.
When you hold a live wire bare foot you get a shock however while wearing plastic or rubber shoes you don't why?
cos plastic and rubber no conduct electric
Why can birds sit on a wire without getting an electric shocked?
You only get an electric shock if you are touching both the ground and the electric wire, (or close enough to both for the electricity to arc) Birds sat on electricity cables are not close enough to the ground for the electricity to arc, therefore they do not get shocked.
Why neutral wire doesn't give electric shock?
The neutral wire doesn't give an electric shock because it is the same potential as ground. That being said if you come in contact with the "hot" wire and the neutral or ground wire, you become the load and will receive a substantial shock.
Why laptop sometimes gives a shock?
It shocks you sometimes because you are touching the shock zone or there is a loose wire. My laptop does that to me.
Why birds do not get electric current when they sit on electric wire?
In order for electricity to shock something it needs to be touching the ground. Electricity goes through the body and back into the ground. Since the crow is in no way touching the ground the electricity has no where to go and thus can not shock the crow. If you touch the wire and are not touching anything that conducts electricity (like metal) and are not touching the ground you will not get shocked either. But if you stand on the ground and touch the wire you will get shocked.
Why the crows are not getting electric shock while they stand on electric line?
The birds are only touching one wire and not touching any thing that provides a return path for the current back to the generator. There is a procedure for people to work on energized high voltage lines from a helicopter without getting shocked because they are only touching one wire, so there is no return path available through the person.
Hazard lights come on when i indicate?
Answer You have a short, or a bare wire touching something within your signal light system or even maybe in your fuse box. Look for a wire that is crimped or bent and see if it's not bare and touching something steel in your car.
Which colored wire gives us electric shock?
Red
