6. A 12 AWG copper conductor has a cross sectional area of A = 3.31 x 106 m². The conductor carries a current of 20A and has a length of 25 meters. If the conductivity of copper is 0=5.8 x 107 S/m and the charge density p= 1.8 x 1010 C/m³, determine a) The current density, J b) The Electric field Intensity E c) The voltage drop d) The resistance of the conductor R e) The drift velocity of conductors 7. A wire loop of area A = 0.15m² is placed in a uniform magnetic field of strength B= 0.002T. The plane of the loop is perpendicular to the magnetic field. After 0.2 seconds, the magnetic field is reduced by half of its initial value to 0.001. Find the magnitude of the average emf induced in the loop during this time using faradays law.
