NEET Physics Resistance & Resistivity MCQ Question
Which of the following statements about series combinations of cells is correct?
The equivalent emf of a series combination is the sum of individual emfs.
The internal resistance of a series combination is the product of individual resistances.
The total current in the circuit is independent of the number of cells in series.
The equivalent emf remains constant regardless of the internal resistance.
Correct Answer
Detailed Explanation
In a series combination of cells, the equivalent emf is indeed the sum of their individual emfs, as mentioned in the NCERT context. The internal resistance adds up as well, contrary to option B.
