What Is The Formula Of Specific Resistance
What Is The Formula Of Specific Resistance. The si unit of viscosity is poiseiulle (pi). Rearranging the above relation, r = v i v i.

List of some quantities and their dimensions: The specific resistance or conductance of the wire material must be known. Viscosity is a measure of a fluid’s resistance to flow.
Note, The Resistance Of The Specified Simple Length Is Calculated.
Rearranging the above relation, r = v i v i. The magnitude of the resistance is called resistivity. According to the definition of resistance, r = v / i.
The Resistance Formula To Calculate The Material Can Be Derived From Ohm’s Law.
The unit of electrical resistance is ohms. You can calculate the value of specific resistance and resistivity by using the online calculator tool. The current flow increases, the resistance acts as a speed breaker to the accelerated car (high current flow).
The Specific Resistance Or Conductance Of The Wire Material Must Be Known.
Get the huge list of physics formulas here. Resistance of a substance= r=ρ al ρ= lra = iv la dimension of v is [ml 2t −3a −1]dimension of i is [a]dimension of a is [l 2]dimenstion of l is [l]thus dimension of ρ is [ml 3t −3a −2] List of some quantities and their dimensions:
We Know That The Electrical Resistance \(R\) And Specific Resistance \(\Rho \) Depend On The Physical Nature Of The Given Material;
Electric charge flows easily through some materials than others. Specific resistivity of conductor depends on the material of the conductor and its temperature. A loudspeaker cable, you have to multiply the value by 2.
\(\Sigma\) = Conductivity \(\Rho\) = Resistivity.
R = volts / ampere. And is abbreviated with the capital letter k or the greek letter ρ (rho). The resistivity formula can be represented as follows:
