Question :- why alternating current is used for conductivity measurement
Answer:- alternating current is used for conductivity measurement because of polarisation it occurs because of migration of the ions in the solution to the surfaces of the electrodes. If a DC voltage is applied, then there will be a voltage drop across this region. The AC voltage and platinized electrodes are used to reduce the effects of solution polarization on the conductivity measurements.
