When referring to electrical conductance, it is used in the application of electricity to equipment. Electrical conductance measures the equipment's ability to conduct electrical charge. A practical application would be to decrease the resistance in an electrical circuit so that the conductance is higher and electricity flows more smoothly.

Why use AC to measure ionic conductance and why not dc current?
in order to avoid electrolysis
Why is conductance G?
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'.
Will a fully charged new battery have a low conductance reading?
No it will have high conductance
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.
The si unit of conductance is?
The unit of electrical conductance is the mho.
What is effect of dilution on conductance?
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.
What are Units of conductance?
Siemens.
What is the conductance of a 4.7 Ohm resister?
Conductance is reciprocal of resistance. Hence, G=1/R. Calculate now
Does the conductometer directly measure the conductance of the solution or it measures individual ion conductance and then sum up?
it directly measures...
What is conductance titration?
Conductance titration works on the principle of ohm's law. If we are to find the strength of a acid then we take that acid into a beaker and dip the electrode of conductometer into the acid solution. This measures the conductance of acid. Now, we titrate this acid solution against the base of known molarity, the conductance starts decreasing. This is due to the binding of H+ ions of acid with the OH- of Base until a point is reached where conductance is minimum. When we move forward the conductance starts increasing again. This is now due to the free ions of Base present in solution. The conductance produced by an ion is proportional to its concentration (at constant temperature),
Is vacuum tube a voltage controlled device?
yes, effectively a voltage controlled conductance. (conductance being the reciprocal of resistance)
How do you find conductance using ohms law?
To find the conductance using ohms law,you take the inverse of the resistance(/R)
