Question

define resistence......

Answer 1

Hello!!

The obstruction offered in the flow of the current is termed as Resistance.

Thanks!❤

Answer 2

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.
