Question

Statement-1 : In a series R,L,C circuit if V subscript R end subscript, V subscript L end subscript , and V subscript C end subscript denote rms voltage across R, L and C repectively and V subscript S end subscript is the rms voltage across the source, then V subscript S end subscript equals V subscript R end subscript plus V subscript L end subscript plus V subscript C end subscript.

Statement-2 : In AC circuits, kirch off voltage law is correct at every instant of time.

  1. Statement-1 is True, Statement-2 is True; Statement-2 is a correct explanation for Statement-1.    
  2. Statement-1 is True, Statement-2 is True; Statement-2 is NOT a correct explanation for Statement-1    
  3. Statement-1 is True, Statement-2 is False    
  4. Statement-1 is False, Statement-2 is True    

The correct answer is: Statement-1 is False, Statement-2 is True


    Statement 1 is false because the given relation is true if all voltages are instantaneous
