The unit of current strength shows how much charge will pass through the cross section of the wire per unit of time. The current strength is denoted by the Latin letter I, it is a scalar quantity. The unit of current strength is determined by the ratio of the charge q passing through the cross section of a metal conductor to the time interval t during which the electric current passed through the conductor. Accordingly, the formula has the following form: I=q/ t

Modern set of repair and construction equipment is hard to imagine without such an important tool as a hammer drill. The principle of its operation is based on the functions of a conventional electric drill, which are expanded by reciprocating impact capabilities. A special mechanism is responsible for them, which converts the rotational movements of the shaft into shock. If repair of the perforator is required, then this particular unit most often fails, because it is subjected to increased loads
