- Answer The following problem. Base on the given Table. Show complete solutions. View ImageIf we have a material with the same electrical properties in all directions, we define its resistivity p (the Greek letter "rho") as the ratio of the magnitudes of the electric field E and the current density J: 0= In vector form, The SI unit of resistivity is one-ohm meter (1 Q-m, where the Greek letter "omega" stands for "ohm"). One ohm equals one volt per ampere (1 0 = 1 VIA). For many materials and devices, Georg Simon Ohm found that J is directly proportional to E at a given temperature. If so, p is constant and we say that the material or device follows Ohm's Law or that it is ohmic. е Calculate the resistivity of a certain metal if an electric field of 7.2 x 10-3 V/m gives a current density of 1.20 x 105 A/m2 he 6.0 x 10-8 ohm-m 7.2 103 ohm-m ware O 1.2 x 105 ohm-m izo. 0.17 x 102 ohm-m icrosoft Teams Click Save and Submit to save and submit.
