# Electric power and internal resistance

isorounded

## 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?

## Homework Equations

Given formulas in laboratory work

## The Attempt at a Solution

[/B]

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

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.
