Question

What factors does the resistance of a conductor depend on?

Answer 1

Resistance:

1. Resistance is a measure of the opposition offered to current flow in an electrical circuit.
2. Resistance is measured in ohms. It is denoted by the Greek letter omega $\left(\Omega \right)$.
3. Mathematically, Resistance $R=\rho .\frac{l}{A}$, Where $\rho$= resistivity, $A$= cross-sectional area , $l$= length of the conductor,
4. The resistance of a conductor depends upon its resistivity, length, and cross-sectional area.
5. It also depends upon other physical factors like temperature etc.

Thus, the resistance of a conductor depends on resistivity, length, and cross-sectional area of the conductor.
