Combination of Cell's or Batteries

EMF of a battery and Terminal Voltage and its relation with each other in different situation(s), such as (a) when discharging in a circuit, (b) in an open circuit and (c) while charging. It is advisable to the students that they must practice numerical problems based on such problems.
When the batteries are connected in series then the current (i) delivered in the circuit is as given below:
When the batteries are connected in series but with similar polarities together, then how one must proceed to such problems can be understood from the discussion as follows:
 Batteries connected in parallel, with similar emf's (E) connected together:
 Different emf's connected in parallel:
