State the factors on which resistance of a material depends ?
Answers
Answer:
The resistance of a conductor depends on the 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.
Answer:
The resistance of a conductor depends on the 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.The resistance of a given piece of wire depends of three factors: the length of the wire, the cross-sectional area of the wire, and the resistivity of the material composing the wire. To understand how this works, think of water flowing through a hose.The resistance of a conductor depends upon the resistivity, length and cross-sectional area of the conductor which is given by the relation (R=ρAl). It does also depend on other physical factors like temperature etc. Its SI unit is Ohm (Ω).
