Five hundred cells of same emf and same internal resistance are connected in series to form a loop in same order (without external resistance). The potential drop across 199 cells is found to be
View answer and explanation
Correct option: D
Zero
Option D is correct. When cells are connected in a loop, the potential drop across any number of cells is zero due to the closed-loop configuration.
