Hi, I love the stuff you show but you are measuring a current in mamp but not the electrical conductivity whichs is in mS/cm or µS/cm what changes of your apparatus could you think of to have an absolute conductivity measurement. Also to be used with acids isn't it best to use carbon rods instead of metal electrodes. Thanks for answering

is the positive terminal of battery connected to the 60mamp bulb? I assumed so from the red colour of the wire used in the circuit

Are the electrons moving through solution? or are you simply doing redox reactions at both electrodes because you are applying 9 Volts!!!!!!!!!, this is enough energy to make chlorine gas, hydrogen, oxygen...........and a multitude of other reactions.

kevin klunder I have tested 9 volt battery in tap water, and it is enough to change the hydrogen from a +1 charge to a 0 charge and separate from the hydroxide ion at the electrodes. Some of the conductivity must be lost because the energy is being used to split molecules.

So he can clearly illustrate that salt water solution conducts electricity better, that current flows through the solution (completing the circuit) and it's not magic.

What do the readings indicate? Voltage or Current? What is the Battery Voltage?

Looks like the readings are current in milliamps (according to the text in the video) and the battery is a 9V battery.

Certainly not the voltage since the battery is 9 volts and the multimeter is in series.
