This calculator calculates the resistivity of a component based on its resistance value, length, and cross-sectional area.
Calculation: Parallel Resistance (Resistor) Calculator Color Code Calculator for Resistors Electric Current, Electric Power, Electricity and Electric Charge The Formula Wheel - Formulas of Electrical Engineering In acoustics we use "Ohm's law as acoustic equivalent" How electricity works. Ohm's Law cle...
understand this definition better, assume that we have a solid cube of copper with us and we measure resistance between any two opposite faces of the cube using an ohm-meter. Then resistance indicated by the ohm-meter is known as electrical resistivity of copper. The formula of resistivity is...
4 formula r = v/i or, r = ρ(l/a) v = voltage, i = current, ρ = resistivity ρ = (r×a)/l r = resistance, l= length, a = cross-sectional area 5 si units the si unit of resistance is ohm the si unit of resistivity is ohm-metre. 6 applications the property of ...
