Measurement of Conductivity of Ionic Solutions- Part 1

The resistivity of a substance can be calculated using a Wheatstone Bridge (the fancy diagram I have drawn 😅). The basic principle of the Wheatstone Bridge is discussed. When we have an ionic solution we come across two problems: 1. The DC leads to a change in the composition near the electrode. This in turn might lead to an increase in resistivity. To mitigate this we use Alternating Current instead. We use a different detector since a galvanometer is not calibrated to detect AC. 2. We cannot connect an ionic solution like a wire. The solution to this problem is discussed in the next video. (Comes out next Monday!) If you have any questions or suggestions comment below!
