Step 1
The electric field intensity (E) can be found using Ohm's law, which states that the electric field intensity is equal to the current density (J) divided by the conductivity (σ). E = J / σ Given that the current density (J) is 5 x 10 A/m and the conductivity Show more…

Q2: conductor that is 5 cm wide and 1 cm tall has a current of 30 A flowing through it , a magnetic field of 15 Tis directed and hall emf of 12 μ volt (a) calculate the electric field in this conductor that is perpendicular to the current ,(b) determine the drift velocity of the electron, (c) calculate the charge density of free electron in this conductor per cubic meter? Ans: EH=2.4×10⁴ volt/m drift velocity of the electron=0.16×10⁴ m/sec n=23.43×10 ¹⁹ m⁻³
