For example, if entering the resistivity value of copper, The same, hard rubber will offer much greater resistance in a circuit than copper.Ī tip to use this calculator is when entering the resistivity value, use Other hand, has a resistivity value of 1 x 10 13. Meanwhile, hard rubber, an insulator, on the As an example, copper, a great conductor, Value, or an insulator, offers much greater resistance. This is because insulators do not allow for easy movement of electrons through them. Insulators, on the other hand, have very high resistivity

They don't offer much resistance in a circuit and allow for free movement of electrons. Conductors, which are materials that conduct electrons well, have low Different materials offer many different values of resistivity. The greater the resistivity of an element, the more resistance it will offer in a circuit. The resistance also is affected by the resistivity of the material, which is the amount of resistance a material intrinsically If the cross-sectional area is very small, this gives much less space for electrons to pass through and they bump and collide into each other,įriction. This equals less resistance in the wire and, thus, This is because if a material has a greater cross-sectional area, it has more space toĪllow electrons to pass through without much collision or friction, since the area is larger for electrons to pass. And conversely, the lower the cross-sectional area, the higher the resistance. The greater the cross-sectional area, the lower the As far as the area, resistance is inversely affected by the cross-sectional area of a material. When going through a shorter length material, they meet up with less resistance, since there is less of Material, they must meet up with more or greater resistance. This is because in a long material, the electrons must go through more of the material. And conversely, the shorterĪ material is, the lower its resistance. The longer a material is, the greater its resistance. The resistance of a material is directly affected by its length. To use this calculator, a user must enter all fields, the resistivity, ρ, of the material, the length, L, of the material, and the cross-sectionalĪrea, A, of the material, and the result will automatically be calculated and The resultant value isīased on the resistivity of the wire or material, the length of the wire, and the cross-sectional area of the wire, according to the formula This resistance calculator calculates the resistance of an electronic component from the resistivity formula. (if resistivity, area, and length are Known)
Resistance Calculator By Resistivity Formula To use this calculator, a user enters the power, P, and either the current, I, or the voltage, V, and the result will automatically be calculated and Or R=P/I 2 (if power and current are known). The voltage which is dropped across it or the current going through it, according to the formulas, R=V 2/P (if power and voltage are known) This resistance calculator calculates the resistance of an electronic component based on the power that the component consumes and either This equation above represents ohm's law.Įnter the Power and Voltage or Current to compute result. The resistance result which is displayed above is in unit ohms (Ω). This resistance calculator calculates the resistance of an electronic component based on the voltage which is dropped across the component and theĪmount of current going through the component, according to the formula, R=V/I.Ī user enters the voltage, V, and the current, I, and the result will automatically be calculated and shown.
