Assertion: Terminal potential difference of a cell is always less than its emf.
Reason: Potential drop due to internal resistance of cell increases the terminal potential difference.
Reason: Potential drop due to internal resistance of cell increases the terminal potential difference.
View answer and explanation
Correct option: D
If both Assertion & Reason are False
Option D (If both Assertion & Reason are False) is correct because the terminal potential difference can be greater than the emf during charging, and the potential drop due to internal resistance decreases the terminal potential difference.
