Resistivity is the electrical resistance of a conducting material per unit length. In other words, it is the degree to which a conductor opposes the flow of electricity through itself, instead allowing the energy to flow out of the electrical circuit, most often as heat. Resistivity is useful ...
Pure water is a poor conductor, but when it contains salts or other impurities, it becomes a better conductor. 8. How can we distinguish between a good conductor and a poor conductor? A good conductor (e.g., copper or silver) allows electricity to pass through with little resistance, whil...
Resistance is mainly dependent on two factors; the geometry of the element and the material. Since electrical current is a continuous flow of electrons through the material the width (diameter) of the conductor affects the resistance, just like the diameter of a pipe determines the maximum flow ...
resistance is the inverse of electrical conduction. The resistance of an object is defined as the ratio of the voltage across the object, to the current flowing through it. The resistance in a conductor depends on the amount of free electrons in the medium. The resistance of a semiconductor ...
Insulators are used to support the conductor, avoidelectric shock, and all those paths where no current is intended. The best insulators are ceramics, plastic, wood, etc. What is Semiconductor? The semiconductor has a resistivity between 10-4 and 104 ohm-meters. At normal temperatures, the res...
The major differences between resistance and reactance are highlighted in the following table ? Basis of DifferenceResistanceReactance Definition Resistance is the measure of opposition offered by a conductor in the flow of electric current. Reactance is the opposition to the flow of alternating current...
Difference Between Resistance and Resistivity Relationship Between Resistivity ρ and Conductivity s Resistivity is a measure of how well a material is at resisting the flow of current just like a frictional force while conductivity is a measure of how well a conductor allows the flow of current th...
resistance is the inverse of electrical conduction. The resistance of an object is defined as the ratio of the voltage across the object to the current flowing through it. The resistance of a conductor depends on the amount of free electrons in the medium. The resistance of a semiconductor ...
Difference Between Resistance and Resistivity • Resistance and resistivity are properties of conductors where resistance is an extrinsic property whereas resistivity is an intrinsic property • This means that resistivity of a conductor is always same and is independent upon its length or size ...
