Resistance of a Conductor refers to the opposition that a material offers to the flow of electric current. It is a fundamental property that determines how much current will flow through a conductor when a voltage is applied.

Resistance of a conductor can be calculated by following tool:-

How to calculate resistance of a conductor

Formula to Calculate Resistance:

R=ρ⋅A/L

where:-

$R$ = Resistance (in ohms, $Ω\Omega$ )
= Resistivity of the material (in ohm-meters, $Ω⋅m\Omega \cdot m$ )
$L$ = Length of the conductor (in meters, m)
$A$ = Cross-sectional area of the conductor (in square meters, $m^2$ )

Key Factors Affecting Resistance:

Material (Resistivity $ρ\rho$ ):

Conductors like copper and silver have low resistivity.
Insulators like rubber have high resistivity.

Length (LL):

Resistance increases with the length of the conductor.

Cross-Sectional Area ( 𝐴 A):

Resistance decreases with increasing area

Temperature:

For most metals, resistance increases with temperature.
For some materials like semiconductors, resistance decreases with temperature.
