Two batteries of emf ε 1 and ε 2 (ε 2 ε 1 ) and internal resistances r 1 and r 2 respectively are connected in parallel as shown.

Question

Two batteries of emf ε 1 and ε 2 (ε 2 > ε 1 ) and internal resistances r 1 and r 2 respectively are connected in parallel as shown.

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.
