How will you prove that the unit of resistivity isohm-metre? |
|
Answer» The SI unit of electrical resistivity is the ohm-meter (Ω⋅m). For example, if a 1 m × 1 m × 1 m solid cube of MATERIAL has sheet contacts on TWO opposite FACES, and the resistance between these contacts is 1 Ω, then the resistivity of the material is 1 Ω⋅m. |
