Homework Statement


Today I did a laboratory work in which I had to find power and internal resistance. I used an ordinary battery so it's closed circuit. I did all tasks except writing a hypothesis and conclusion I can't really think of it. I don't know what to write since I just measure using voltmeter and ammeter and then calculate Electric power and internal resistance. That's it. Can someone suggest anything pls?

I was thinking to relate given formulas with ohm's law and formula.

The image did not Upload correctly. Can you try again? Be sure it is of a supported file type. Are you using the PF phone app, or are you using a browser to try to do the Upload?

Well, you need to show us your work first -- that is in the PF rules (se INFO at the top of the page). You also need to define those symbols -- we could try guessing, but that will waste a lot of time.
