A Copper wire with length of 400 m and cross section area of 3.4 mm², (1) what is the resistance of the wire? (2) When 68-Volt potential difference is applied over the wire, what is the current through the wire? (3) What is the current density? (4) What is the electric power? (5) What is the drift velocity, if the number density of electrons is 1022 m-3 (The resistivity of copper is 1.7x10-8 Ohm m.) For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).
