What' s an electric shock?

• It' s a phenomena that occurs when a person comes into contact with an electrical energy source. Electrical energy flows through a portion of the body causing a shock.

• It' s a phenomena that happens when you are going to create electric current. It' s the first step of it.

• It' s an emergency signal for warning us about some electric current is near us.
