In Polarography for each voltage applied across the cathode and anode, we measure the current in terms of micro amperes (\(\mu A\)). If we plot a graph of i vs V. The graph thus obtained is known as polarogram. The nature of the graph is S shaped, and is commonly called as Polarographic wave. The graph is not smooth and steady, but shows some periodic oscillations or fluctuations. These fluctuations are due to growth and fall of Hg drop. As soon as drop starts growing, more and more is the, reduction of metal ions on the surface of DME so more will be the magnitude of the current. When the size of drop is maximum, the deposition is maximum and the current is maximum. When the drop falls, the current falls to zero i.e. minimum. Again new drop formation takes place and current starts increasing. This trend is periodic.

Don’t want your columns to simply stack in some grid tiers? Use a combination of different classes for each tier as needed. See the example below for a better idea of how it all works.

For grids that are the same from the smallest of devices to the largest, use the .col and .col-* classes. Specify a numbered class when you need a particularly sized column; otherwise, feel free to stick to
