Question

Two batteries of emf ℰ₁ and ℰ₂(ℰ₂ > ℰ₁) and internal
resistances r₁ and r₂ respectively are connected in parallel
as shown in figure.
(a) Two equivalent emf ℰₑq of the two cells is between e₁
and ℰ₂, i.e., ℰ₁ < ℰₑq < ℰ₂
(b) The equivalent emf ℰₑq is smaller than e₁
(c) The ℰeq is given by ℰₑq = ℰ₁ + ℰ₂ always
(d) ℰₑq is independent of internal resistances r₁ and r₂

Answer 1

Answer:

Two batteries of emf ℰ₁ and ℰ₂(ℰ₂ > ℰ₁) and internal

resistances r₁ and r₂ respectively are connected in parallel

as shown in figure.

(a) Two equivalent emf ℰₑq of the two cells is between e₁

and ℰ₂, i.e., ℰ₁ < ℰₑq < ℰ₂

(b) The equivalent emf ℰₑq is smaller than e₁

(c) The ℰeq is given by ℰₑq = ℰ₁ + ℰ₂ always

(d) ℰₑq is independent of internal resistances r₁ and r₂
