The unit of specific resistance is ohm-metre.
What is a specific resistance?
noun. 1. the electrical property of a material that determines the resistance of a piece of given dimensions. It is equal to RA/ l, where R is the resistance, A the cross-sectional area, and l the length, and is the reciprocal of conductivity. It is measured in ohms.
What is the unit of specific resistance in CM?
The unit of resistivity can be obtained when resistance R is expressed in Ohm (Ω) and distances are expressed in centimeters (cm). Here, the SI unit of resistivity will be Ohmcm (Ω . cm).
What is the unit of specific resistance class 10?
In this convention, the unit of resistivity is Ohmcm (Ω . cm) . If the distances are expressed in meter (m), the SI unit of specific resistance is given by Ohmm (Ω . m) .
What is the formula for specific resistance?
The specific resistance of copper is a good conductor at 1.72 x 10-8 ohm meter as well as the specific resistivity of air is a poor conductor at1. 5 x 1014 ohm meter. Thus, the specific resistance of a conductor is the unit length & cross-section area of the conductor’s resistance.
What is unit of specific conductivity?
Conductivity (or specific conductance) of an electrolyte solution is a measure of its ability to conduct electricity. The SI unit of conductivity is Siemens per meter (S/m).
What is specific resistance and state its SI unit?
Specific resistance is also known as resisitivity. The resistivity of a material is the resistance of a wire of that material of unit length and unit area of cross-section. Its S.I. unit is ohm-metre.
