Question:
Two batteries of emf ε1 and ε2 and internal resistances r1 and r2 respectively are connected in parallel as shown in the figure.
(a) the equivalent emf εeq of the two cells is between ε1 and ε2 that is 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
Solution:
The correct answer is (a) the equivalent emf εeq of the two cells is between ε1 and ε2 that is ε1 < εeq < ε2
