Question

In which of the following case current shown by ammeter is maximum

  1. S1 , S2 ,S3 closed    
  2. S2 , S4 ,S5 closed    
  3. S1 ,S3 ,S5 closed    
  4. S2 , S3 ,S4 closed    

The correct answer is: S1 ,S3 ,S5 closed


    Current is maximum when resistance in the circuit is minimum. i.e. when S1 ,S3 ,S5 are closed because then all resistances will be short circuited I subscript m a x end subscript equals fraction numerator V subscript 0 end subscript over denominator R end fraction
