The Potential difference between the terminals of cell H is (A) Equal to 1V

Question

Figure shows four cell E, F, G and H of emfs 2V, 1V, 3V and 1V and internal resistances 2Ω, 1Ω, 3Ω and 1Ω respectively

The Potential difference between the terminals of cell H is 

(A) Equal to 1V 

(B) More than 2V 

(C) Between 1.5V and 2V 

(D) Between 1V and 1.5V

Answer 1

The correct option (D) Between 1V and 1.5V  

Explanation:

P.D. between terminals of cell H = 1 + (1 × I₂)

= 1 + (6/13) = (19/13) = 1.46V
