Grouping of Batteries (in hindi)
Lesson 10 of 25 • 0 upvotes • 12:22mins
Rajesh Kumar
Grouping of batteries in this lesson we have learnt about combination of batteries that is series combination and parallel combination. In series combination equivalent emf is addition of individual emf and equivalent internal resistance is addition of individual resistance of the batteries.hence equivalent emf and resistance is greater than any individual . In parallel combinations equivalent emf is sum of the ratio of individual emf by resistance divided by sum of reciprocal of resistance.equivalent resistance same as in case of parallel combination of resistance.that is final emf is equal to individual but resistance decreased by n times for n batteries.
