Web29 de abr. de 2014 · Resistance depends upon: (i) Length of the conductor (ii) Area of cross section (iii) Material of conductor (iv) Temperature of conductor. Resistivity depends on: … WebThe resistivity goes right here. So, the bigger the resistivity, the bigger the resistance. That makes sense. And then it also depends on these geometrical factors of length and area. So, here's a formula to determine what factors actually change the resistance of a resistor. The resistivity, the length, and the area.

The effectiveness of irrigation-water management depends on knowledge of the agricultural soil texture . The content of fines particles and sand, and therefore the soil porosity, determines the water holding capacity. WebThe resistance of a conductor depends mainly on three factors, they are length, area of cross-section and resistivity of the conductor. Resistivity of the conductor, also known as specific electrical resistance, is the measure of the …
Web30 de set. de 2024 · On what factors resistivity depends? The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size. The SI unit of electrical resistivity is the ohm-meter. Hence resistivity is dependent on the temperature. What is meant by 1 ohm? WebThe resistivity ρ of a material depends on the molecular and atomic structure and is temperature-dependent. For many good conductors, resistivity increases with increasing temperature. Variation of Resistivity in Conductors In conductors, valence electrons are loosely bound to the nucleus.

Web28 de mai. de 2024 · The resistivity of a material depends on its nature and the temperature of the conductor, but not on its shape and size. A good conductor has less resistivity, whereas a bad conductor or insulator has high resistivity. The resistivity of semi-conductors lies between that of conductors and insulators.
WebThere are several factors on which resistance depends which are follwing :- 1. Resistivity :- Resistance depends upon resistivity which is a proportionality constant and depends on nature of substance and temperature. 2. Temperature :- As the temperature increases, the value of resistivity increases so resistance increase Continue Reading 81 1 1 red pine shrubWebOn what factors does the resistivity of a material depend ? red pines b\u0026b speculator nyWeb12 de jun. de 2024 · Resistivity (ρ): It can be defined as the resistance of a conducting material per unit length with unit area of cross- section.
