Combination of Batteries: Practice Problem & Solution
Assertion (A): When identical cells are connected in parallel to the external load, the effective emf increases. Reason (R): All the cells will be sending unequal current to the external load in the same direction.
Solution Explained:
To solve this problem, we apply the core principles of Combination of Batteries. Understanding the underlying formula is key to arriving at the correct answer below:
When identical cells are connected in parallel, the effective EMF remains the same as that of a single cell, while the current capacity increases. Thus, Assertion (A) is false. For identical cells, current distribution should be equal. Thus, Reason (R) is also false.
