Ok i get it now, thanks. I think i can calculate emf and r now from the equations.

Do you want me to show you the diagram? I cannot show you but i have it drawn. The I in both cases are 1.2 and 0.76 ohms. 1.2=x:(3+y) 0.76=x:(5+y) do you mean like this? How to solve them? Do i use the sum method or something?

Circuit consisting of battery, switch, resistance and a voltmeter. We take 2 measurements. One with a resistance of 3 ohms, there's voltage of 3.6 volts. Second with a resistance of 5, there's a voltage of 3.8 volts. Calculate the EMF, internal resistance and short-circuit current(sorry i didnt...

Thank you for your answer. I think this cleared my head.

Thats what i thought, but what if the circuit has no consumer, can the equatiuon work then ?

As the title states, can EMF = I = const ?

There is a second measurement which is with a resistance of 5 and a voltage of 3,8. I am not sure if that helps. Also the electric circuit consists of a switch, battery, resistance and an internal voltmeter ( not sure about the internal part but it is on the inside of the circuit and not the...

Homework Statement I need to calculate EMF and internal resistance from the given resistance and voltage. R = 3 ohms U = 3,6 V EMF- ? I0 - ? r - ? Homework Equations I = U/R EMF = A/q I = EMF/R+r I0 = EMF/r The Attempt at a Solution I = 3,6/3 = 1,2 A I = EMF/R+r 1,2= EMF/3+r ^ I hit a wall...

so, by my calculations x5 = 5.68 ?

so k is 420 and b is -50, the first 3 entries agree with me on this one, but i am not fluid in mathematics in english so i can't understand what you mean, do you mean xy=k+bx, sorry, and also do you think the number 24 fits in the table or is it a mistake ?

Well its mostly because the x-8 is in the end so i thought that the missing x'es were [4;7], but now i think it might not be true because the results don't match. I don't want to believe that there's a mistake in the table tho. I also thought that why are the x'es unknown if it were from 1 to...

I just figured out something but I am not sure, if k is 420 and b is -50 then it goes correctly by the table but it gets wrong at the 24, because 420/5 -50 is 34 not 24. Can it be a mistake in the table or is there smth I am mistaken in ?

the ones in y are different, but i believe that the ones in x might be the same, because 1;2;3 right and the last is 8 not any other number. oh and yea i guess its exact fit if yu mean like 2 or 3 not 2,5 or 3,5

Homework Statement there's a table x - 1;2;3;u;u;u;u;8 y - 370;160;90;u;24;u;u;u u - unknown value i have to complete this table with this equation y=(k/x)+b you have to find k and b values Homework Equations y=(k/x)+b x is relevant to...

You want me to put numbers in those equations or understand how i got the combinations, i have a hard time understanding what comes next.
