Task id16530
Find the internal resistance and voltage at the terminals of the element with emf. E = 2.1 V, located at a distance l = 20 m from the consumer of electrical energy, if with a consumer resistance of R = 2 Ohms, the current in the circuit is I = 0.7 A. The wires are made of copper conductor with a diameter of d = 1.2 mm; resistivity of copper p = 0.017 μOhm m.
