Answer:B
In conductivitimetric method, to measure the conductivity of the cell, 5V ___________ is applied across the electrodes.
A. DC B. AC C. Pulsating DC D. DC or AC
Explanation: In conductivitimetric method, to measure the conductivity of the cell, 5V alternating current is applied across the electrodes. This is because alternating current avoids polarisation.
