WebSep 12, 2024 · The resistivity of a material is a measure of how strongly a material opposes the flow of electrical current. The symbol for resistivity is the lowercase Greek letter rho, ρ, and resistivity is the reciprocal of electrical conductivity: ρ = 1 σ. The unit of resistivity in SI units is the ohm-meter (Ω ⋅ m. WebElectric charge and current are related quantities but they are different from each other. The main difference between current and charge: Current: It is the rate of flow of charge (generally electrons). Current (I) is the physical quantity measured in amperes (A). Charge: It is the deficiency or excess of electrons on a body surface. fun healthy mealsWebCurrent density is a quantity related to electric current. The symbol for current density is J (bold). As a vector, current density has magnitude and direction. By definition, current density is the product of charge density (ρ) and velocity (v). The magnitude of current density is also equivalent to the ratio of current (I) to area (A). girl version of andrew
