In the series combination of 
cells each cell having emf 
and internal resistance 
. If three cells are wrongly connected, then total emf and internal resistance of this combination will be
A
B
( 
), nr
), nr C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
Since due to wrong connection of each cell the total emf reduced to 
then for wrong connection of three cells the total emf will reduced to 
whereas the total or equivalent resistance of cell combination will be nr.
