Hello o'great chemists and electrochemist, I have a 2 part question--Part 1-As a chemist would you agree that electrolysis of water can be used to verify the results of a electrical test meter (Fluke power analyzer) that shows a difference in total electrical power output of 2 test circuits.
 
The test is based on Faradays law , to paraphase, In electroylysis the substance produced is proportional to the amount of electricty (electrons) used.

In our testing of the 2 circuits called A & B, if A "produces"  more gas  than the B, would this mean that that A had a higher total power output??

Part 2--In basic electrolysis of water, would 1 watt in AC at 10 to 20 hz produce more gas than 1 watt DC???  

Please help Im trying to prove the results of an experiment to a elec. engineering instructor who dosnt believe the results of his own test equipment....

Thanks Brad F

almost forgot ---the 1 watt AC is at 10 to 20 cycles per minute!!!!

Think about double layer charging, think about potential needed for oxygen and hydrogen evolution. Do the gases evolve during whole cycle? Do solution gets hot? Is all energy used for water electrolysis?

These are factors (probably not all) that have to be taken into account to answer the question.
