NEETPhysicsAlternating Current

Box may have any series combination of (L, C ) and R. Column-I represents source current and column-II represents possible statements.

Options

  1. A( A P , B R , C PS , D P )
  2. B( A PT , B R , C PS , D PQ )
  3. C( A PT , B PR , C P , D PQ )
  4. D( A P , B PR , C P , D T )

Correct answer

B. ( A PT , B R , C PS , D PQ )

Step-by-step solution

For (A) : Current and voltage are in phase ( ) only R or RLC in resonance. For (B) : Current leads voltage by ( 2 ) only C ( ) power factor (=0 ) For (C) : Current leads voltage ( RC ) or RLC with (X_C>X_L ) For (D) : Current leads voltage ( R L ) or RLC with (X_L>X_C )
