Learn about current and resistance, factors affecting the flow of current, and derivation of the dimensional formula of resistance.
The dimensions of electrical resistance are: [M][L]2[T]−3[I]−2. where, M → Mass. L → Length. T → Time. I → Electrical Current. In terms of base quantities, electrical resistance can be represented as: kg m2 A2s3. The SI unit of resistance is Ohm ( Ω ). What is Resistance?
Jul 31, 2023 · The dimensional formula of resistance is derived from the formula Resistance (R) = Voltage × Current^-1. The formula for voltage is substituted into this equation to get the final dimensional formula for resistance.
Nov 2, 2019 · In this article, we will find the dimension of Resistance. The dimensional formula for Resistance is. [M 1L2T −3I −2] [ M 1 L 2 T − 3 I − 2] Where. M -> Mass. L -> Length. T -> Time. I -> Current. We would now derive this dimensional formula.
Feb 20, 2022 · For a given shape, the resistance depends on the material of which the object is composed. Different materials offer different resistance to the flow of charge. We define the resistivity \(\rho\) of a substance so that the resistance \(R\) of an object is directly proportional to \(\rho\).
Aug 19, 2023 · Resistivity. When a voltage is applied to a conductor, an electrical field →E is created, and charges in the conductor feel a force due to the electrical field. The current density →J that results depends on the electrical field and the properties of the material. This dependence can be very complex.
The resistance is a measure of how difficult it is to pass current through a wire or component. Resistance depends on the resistivity. The resistivity is a characteristic of the material used to fabricate a wire or other electrical component, whereas the resistance is a characteristic of the wire or component.
