NEET Questions / Physics

A cell of emf E and internal resistance r is connected across a variable external resistance R. The graph of terminal potential difference V against current I reaches a maximum value of V. What is the relationship between E, r, and this maximum value of V?

V = E/2

V = E

V = 2E

V = E/r
