Resistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l;ρ = RA/l. The unit of resistance is the ohm. What is cross-sectional area of...

The element's resistance must be increased to achieve a higher voltage drop. Every electric circuit has electric wires. The wire's resistance (R) depends on its length (L), cross-section area (A), and the resistivity constant ({eq}\rho {/eq}) of the wire's material given by the ...
This is very useful in calculating the resistance values of the material at various temperatures. Resistance and resistivity both terms are related to the opposition experienced by a flowing current but it is an intrinsic property of the materials. All the copper wires irrespective of their length ...
Like Ohm’s Law Pie Chart shown above, we can condense the individual Ohm’s Law equations into a simple matrix table as shown below for easy reference when calculating an unknown value. Ohm’s Law Applications The main applications of Ohm’s law are: To determine the voltage, resistance or...
To enable resistivity figures to be meaningful, specific units are used for resistivity, and there are formulas for calculating it and relating it to the resistance in Ohms for a given size of material. Materials that conduct electrical current easily are called conductors and have a low resistivi...
example calculation will help to cement the ideas introduced so far. For a length of copper wire, with a length L = 0.1 m and a cross-sectional area A = 5.31 × 10−6m2and a resistance of R = 3.16 × 10−4Ω, what is the resistivity ρ of ...
