Resistance:-

It is the property of a conductor to resist the flow of charges through it.

Its S.I unit is ohm (Ω).

R = V/I

And here,

  • R = Resistance

  • V = voltage and

  • I = current.

Factors on which the resistance of a conductor depends:

  • Resistance depends on its length (L)

  • Resistance depends on its cross sectional area (A)

  • Resistance depends on the nature of material

\sf{ \pink{R\propto \dfrac{L}{A}}}

\sf{ \red{R=\rho \dfrac{L}{A}} }

Where "ρ" (rho) is proportionally constant known as resistivity of the material of conductor.
