Two batteries of A. The equivalent emf εeq of the two cells is between ε1 and ε2, i.e. ε1< εeq < ε2.
B. The equivalent emf εeq is smaller than ε1.
C. The εeq is given by εeq = ε1 + ε2 always.
D. εeq is independent of internal resistances r1 and r2.
And are in parallel connection.
The equivalent emf will be
The equivalent emf depends on the and . So option D. is wrong.
Equivalent emf is not equal to ε1 + ε2. So option C. is wrong.
From the above equation is can’t be smaller than ε1. So option B. also wrong
So option A. is the correct answer.
