Two cells A and B each of e.m.f 2 V, are connected in series to an external resistance R = 1 . If the internal resistance of cells A is 1.9  and that of B is 0.9 , what is the potential difference between the terminals of cell A?
  • a)
    2 V
  • b)
    3.8 V
  • c)
    0
  • d)
    None of the above

using the Kirschoff's Loop law:
I + 0.9I -2 + 1.9I - 2 = 0
I = 4/3.8
A thus potential drop across 1.9 ohm resistor: 1.9 * 4/3.8 = 2 V
hence the potential difference of battery A in the circuit will be: 0 V
