Question

In the circuit shown E, F, G and H are cells of e.m.f. 2V, 1V, 3V and 1V respectively and their internal resistances are 2capital omega, 1capital omega, 3capital omega and 1capital omega respectively

  1. V subscript D end subscript minus V subscript B end subscript equals negative 2 divided by 13 V    
  2. V subscript D end subscript minus V subscript B end subscript equals 2 divided by 13 V    
  3. V subscript G end subscript equals 2 l divided by l 3 V equalspotential difference across G    
  4. V subscript H end subscript equals 19 divided by 13 V equalspotential difference across H.    

The correct answer is: V subscript D end subscript minus V subscript B end subscript equals negative 2 divided by 13 V
