 Single battery       Two in series  

 

Start by measuring the single batteri having an internal resistance r and emf e
After that make measurements on the series of two such batteries. Use the slider to vary the outer resistance R.

Which connexion do You find between eseries and e
Which connexion do You find between rserie and r
Which connexion do You find between Imax,serie og Imax?

(Answer).

(Remark: r is not pictured - it is a part of the battery symbol).

 Single battery       Two in parallel  

 

Start by measuring the single batteri having an internal resistance r and emf e
After that make measurements on the parallel
of two such batteries. Use the slider to vary the outer resistance R.

Which connexion do You find between eparallel and e
Which connexion do You find between rparallel and r
Which connexion do You find between Imax,parallel and Imax?
