GROUPING OF CELLS

Grouping of cells

Series : 

Eeq = 

and   

.

If  S number of identical cells each of marking (E, r) are connected in series across an external resistor  R.

 

and 

.

Out of these S cells if x number of cells are reversely connected then

Parallel:

If P number of identical cells each of marking (E, r) are connected in parallel across an external resistor R

For unidentical cells in parallel

 and     

 .

Mixed Grouping:

Let S number of identical cells having marking (E, r) are connected in series in a row and there are P such rows are connected in parallel across an external resistor R. Then

 

 

This current I is maximum when  

,

 So 

 or .
