Conductance (G) is a measure of how easily an electric current can flow through a material. It is the reciprocal of resistance (R), with the formula G = 1/R. Conductance is important in electrical engineering and physics as it quantifies the ease with which charges can move through a medium. Higher conductance indicates lower resistance and better electrical conductivity.

SteveThe 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.
Ah, conductance G is like a friendly river flowing smoothly. It helps electricity move through a material with ease, like a happy little stream. Just like how a brush glides on a canvas, conductance allows electrons to travel without resistance, creating beautiful connections in circuits.

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.
