Set the Length to 10 cm and record this value in the space provided above Table 2. The electrical resistance of a wire would be expected to be greater for a longer wire, less for a wire of larger cross sectional area, and would be expected to depend upon the material out of which the wire is made. Use resistivity to calculate the resistance of specified configurations of material. To sum it up: resistance is a property of a given object, resistivity is a property of a given material and sheet resistance is a filthy-but-useful engineering shortcut that treats shape as a unit. Since the cylider’s cross-sectional area increases by the square of the factor, all the factors in the equation cancel out, leaving you with 1*the original equation, i.The lower the resistivity, the larger the current density produced by a given electrical field.The resistance of an object demonstrates similar temperature dependence as resistivity since resistance is directly proportional to resistivity.Schlagwörter:The ResistanceResistance and ResistivityResistance PhysicscomEmpfohlen basierend auf dem, was zu diesem Thema beliebt ist • Feedback
