What is the Effective EMF of 2 Cells in Parallel with Zero Internal Resistance?

AI Thread Summary
The effective electromotive force (emf) of two cells connected in parallel with zero internal resistance is determined by their individual emfs. If both cells have equal emfs, the effective emf remains the same as that of either cell. In cases where the cells have different emfs, the effective emf is equal to the higher emf. The discussion emphasizes that all cells inherently possess internal resistance, making division-by-zero scenarios impractical. Therefore, for two cells in parallel, the effective emf is simply the greater of the two.

what is the Effective emf of 2 cells with zero internal resistance connected in parallel

Good morning mksrpillai, welcome to Physics Forums.

All cells have internal resistance.

It is not a good idea to try to use division-by-zero scenarios as anything other than to show how pointless division-by-zero scenarios are.
 
The concept of internal resistance applies to all electrical sources.

If two cells of equal emf s are connected in parallel then the effective emf is equal to the emf of anyone of the cells.
If two cells of different emf are connected in parallel then the effective emf is equal to the
emf of the cell which is having greater emf. so in ur case E1is the effective emf.
