Use: μ= 4T x 10-7 Hm-1, electron charge = -1.6x10-1⁹ C Question 1 A current of 4.0 A flows through a wire. Calculate the flux density at point 10 cm from, and at right angles to the wire.

A wire with length 100 m and radius 12mm.A current passing in it with 20 A.Calculate the current density inside the wire

ela R L 2L lenda 6 Pail 1) Consider two cylindrical copper resistors (wires). The shorter wire length L and radius R. The longer wire has length 2L and radius. a) Call the resistance of the shorter wire Rs and the resistance of the longer wire RL. What is RL in terms of Rs b) At a Constant voltage V what are the respective currents Is and IL in terms of Rs or RL? Which has a greater current.
