Only if you _exactly_ duplicate the apparatus. After a
quick read thru, this looks to me like it's by someone just
learning to do scientific experiments. It's useful mostly
as a learning experience for the original experimenter, as
the derived equations are not general. They appear to apply
only to the apparatus used to collect the data.

You could take the same type of data on your own setup, use
the same curve fitting techniques and see how they compare.

One way of thinking about resistance is as restriction to
the flow of current. Imagine a hose flowing water. Large
diameter hoses have lower resistance and flow more water at
a given pressure. Long skinny hoses have higher resistance
and flow less water at the same pressure.

If you increase the pressure, more water will flow in any of
the hoses. If you crimp a hose by bending it, you will
increase the resistance and the flow will decrease. If you
completely stop the flow, the resistance is infinite.

An electrical circuit is analogous, with voltage
representing pressure and current representing flow.
The resistor is like a hose carrying electrons instead of
water.

Energy lost to resistance always shows up as heat. The
amount is always the voltage drop across the resistance
times the current through it.. Watts = Volts times amps.

Corrosion is another matter. In a battery, it actually
generates electricity.

Look up DC circuits and Ohms law for a more complete
explanation of what's going on.

I think the experimenter was trying to show that ionic
conduction occurs in both solids and liquids. It doesn't
have much to do with generating hydrogen in general.
