Electricity always tries to find the easiest path to the ground.
Electricity flows easily through water.
The human body is 70 percent water.
These three facts add up to a very dangerous situation for anyone who gets too close to an electrical current.

Many people think if they are shocked, they can pull away and not get hurt. But electricity travels at the speed of light, so a person has virtually no chance of pulling away without injury.

An electric shock affects the body in several ways:

Muscle contractions lock the victim into the circuit.
Chest muscles contract, causing difficulty breathing and unconsciousness.
Heartbeat is interrupted and veins are constricted.
Burns occur at the entrance and exit points of the current.
Partial or total paralysis.
