How to measure?
How can we measure this force which seems to be flowing through the wire and causing bubbles on the copper?

- If you disconnect the wires again then will the bubbles go away?(6 votes)
- I still don't get it. How does it happen?(4 votes)
- When you dip electrodes in water, the positive cathode attracts the polar hydrogen, and vice versa with the anode and oxygen. This causes water molecules to break apart. The liberated hydrogen forms small bubbles at the cathode.(1 vote)
- If on the end of one wire we stick copper and on the other end zinc and put in vinegar ?
What will be the result(1 vote)
- Does this happen only in zink and copper?(1 vote)
- How come when the alligators were not connected there was no bubbles on the wire and when the alligators connected there were bubbles on the wire?(1 vote)
- My question is how did they find out a why of making battery.(1 vote)
- I watched the video on Discovery of Electromagnetism so the answer for how can we measure this force which seems to be flowing through the wire and causing bubbles on the copper?Is use a battery?(1 vote)
- How do the bubbles on both zinc and copper form?(1 vote)
- What would happen to the Zn nail once the wires are connected?
Will the bubbles on copper wire still be there or would they vanish?(1 vote)
- If bubbles are produced on copper wire do they go off from zinc nail?(1 vote)
- I don't know the reason but If you will watch the video carefully then you can see that bubbles are still being produced on zinc..(1 vote)
