Conductance is an opposition of Resistance and it is denoted by G. It is given by the relationship G = 1/R . In past the unit of conductance was (mho) which is opposite to (ohm). But these days the unit of conductance is Siemens which is denoted by 'S'.

The symbol G is used to represent conductance because it is the reciprocal of resistance. Conductance is a measure of how easily electric current can flow through a substance, whereas resistance is the measure of how much a substance inhibits the flow of current. Using G as the symbol for conductance helps to easily convey this relationship in electrical equations.

How are specific conductance and equivalent conductance related to concentration of electrolyte?
Specific conductance is directly proportional to the concentration of electrolyte, while equivalent conductance is inversely proportional to the concentration of electrolyte. This is because specific conductance is the conductivity of a solution normalized to a unit concentration, while equivalent conductance is the conductivity of a solution containing one equivalent of the electrolyte.
The si unit of conductance is?
The SI unit of conductance is the siemens (S), named after the German inventor and scientist Werner von Siemens. Conductance is the reciprocal of resistance and is a measure of how easily an electrical current can flow through a material.
How does the concentration of electrolytes affect the conductivity of a solute?
The conductance of a given conductor, C = La/l ..(i)\ L = l/Ra ..(ii)The resistance is expressed in units of ohm, the conductance has units of ohm-1 or mho.The conductance of solutions is also governed by the same relations. From (i), if l = 1,a = 1, the specific conductance L = C. That is,the specific conductance (L) is the conductance of the solution enclosed between two electrodes of 1 sq. cm area and 1 cm apart. when you dilute the solution the concentration decrease and the specific conductance also decreaseThe conductance of a solution depends upon the number of ions present and hence on the concentration. To compare the conductivity of different solutions, it is necessary to take the concentration of the solutions into consideration. It is done by using equivalentconductance, l.
Why equivalent conductance increase with dilution whereas specific conductance decrease?
the specific conductance of the electrolyte falls because of the no of current carring particles i.e. ions present per centimetercube of the soltion becomes less and less on dilution how ever increase in eqi bacause it is the product of specific conductance and rthe volume v of the sol contain 1 gm of eq electrolyte or one mole of the elecrtrolute that's why .............................................
How stomatal conductance is measured by porometer?
A porometer measures stomatal conductance by determining the rate of water vapor movement through small pores on plant leaves. The device creates a small gradient of water vapor concentration and measures the rate at which water vapor diffuses through the leaf surface, providing a direct measurement of stomatal conductance.
What is conductance?
The word conductance is defined as the reciprocal of resistance. It is inversely proportional to the resistance. Mathematically, it can be expressed as: G=(1/R) or G=(R/z^2)
What is the conductance of a 4.7 Ohm resister?
Conductance is reciprocal of resistance. Hence, G=1/R. Calculate now
Using ohm's law express conductance in terms of current and voltage?
Conductance (G) is the reciprocal of resistance (R), expressed as G = 1/R. According to Ohm's Law, resistance is equal to voltage (V) divided by current (I), so R = V/I. Therefore, conductance can be expressed as G = I/V.
What is the symbol for conductivity?
I think it's an inverted omega (Ω) symbol. The Ω symbol is the symbol for resistance the opposite of conductance.
Why is conductance representted by the letter g?
No particular reason. Perhaps because the upside-down omega looks a bit like a gamma. Conductance in Mhos now is measures in Siemens (S).
What is the difference between specific conductance and equivalence conductance?
Specific conductance is the conductance of a specified length of a substance, typically 1 cm, while equivalence conductance is the conductance of all ions produced by one mole of an electrolyte in solution. Specific conductance is a property of the substance itself, whereas equivalence conductance is a property of the electrolyte in solution.
What are the 4 primary constant and secondary constant of transmission lines?
resistance (R) inductance(L) capacitance(C) shunt conductance(G)
What happens to the current if the conductance decreases?
If conductance decreases, the current flowing through the circuit will also decrease. Conductance is the inverse of resistance, so decreasing conductance means increasing resistance, which impedes the flow of current.
Will a fully charged new battery have a low conductance reading?
No it will have high conductance
Why you caluculate the corrected conductance?
Corrected conductance is calculated to account for the impact of temperature on the conductance of a substance. Conductance is temperature-dependent, so correcting for this allows for a more accurate comparison of values across different temperatures. It helps to standardize conductance measurements and make them more reliable for analysis.
Why conductance is ignored in transmission lines?
Conductance is ignored in short circuit studies because the inductance of the line is the dominant value. Conductance may not be ignored in stability studies.
How does a multimeter mesure the amount of electrolytes in a drink?
A multimeter cannot directly measure the amount of electrolytes in a drink. Electrolyte concentration in a drink is typically determined using specific laboratory tests or analytical instruments designed for that purpose, such as ion-selective electrodes or chromatography techniques.
