The resistance of a conductor depends onthe cross sectional area of the conductor, the length of the conductor, and its resistivity. It is important to note that electrical conductivity and resistivity are inversely proportional, meaning that the more conductive something is the less resistive it is...
1.The sensitivity of the bridge circuit depends to a great extent on the ratio of the lead-in conductor and transducer resistances. Thus, the sensitivity will be reduced by the order of 20–30% for Rc/doi:10.1007/BF01409254V. V. Shabarov...
The effects depend on conductor size, frequencyfof the current, resistivity ρ and permeability μ of the material. For a circular conductor of diameterdthe increase of effective resistance is proportional tod2fμ/ρ. At power frequencies and for small conductors the effect is negligible. It may,...

the flow of electric current. it is also defined as the ratio of the voltage applied to the electric current flowing through it. the resistance of a conductor depends on the length, area of cross-section, and the nature of the material used in the conductor’s manufacturing. for a ...
Resistance also depends on the material of the conductor. See resistivity. The resistance of a conductor, or circuit element, generally increases with increasing temperature. When cooled to extremely low temperatures, some conductors have zero resistance. Currents continue to flow in these substances, ...
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 mostly depends on the ...
The Fourth Law states that “the conducting material depends on its temperature”. According to this law when the temperature of a metallic conductor is increased, it’s value also increases. From the first, second and third law, the resistance of a material can be given asR ∝ L/A ...
