Therefore, for such a mistake it is very easy and you can tell that no theoretical knowledge is not able to prepare the employee to perfect the profession, because of some random events can not be predicted.
A lineman (American English) or linesman (British English), also occasionally called a lineworker, powerline technician (PLT), or a powerline worker, is a tradesman who constructs and maintains electric power transmission and distribution facilities.The term is also used for those who install and maintain telephone, telegraph, cable TV and more recent fiber optic lines. The term refers to those who work in generally outdoor installation and maintenance jobs.
Those who install and maintain electrical wiring inside buildings are electricians.Źródło: https://en.wikipedia.org/wiki/Lineman_%28technician%29
Electricity is the set of physical phenomena associated with the presence and flow of electric charge..Electricity gives a wide variety of well-known effects, such as lightning, static electricity, electromagnetic induction and electric current.
In addition, electricity permits the creation and reception of electromagnetic radiation such as radio waves. In electricity, charges produce electromagnetic fields which act on other charges.Electricity occurs due to several types of physics: electric charge: a property of some subatomic particles, which determines their electromagnetic interactions.
Electrically charged matter is influenced by, and produces, electromagnetic fields, electric charges can be positive or negative. electric field (see electrostatics): charges are surrounded by an electric field.The electric field produces a force on other charges.Changes in the electric field travel at the speed of light. electric potential: the capacity of an electric field to do work on an electric charge, typically measured in volts. electric current: a movement or flow of electrically charged particles, typically measured in amperes. electromagnets: Moving charges produce a magnetic field. Electric currents generate magnetic fields, and changing magnetic fields generate electric currents.Źródło: https://en.wikipedia.org/wiki/Electricity
