In an LCR series circuit, if the angular frequency is gradually in creased then match the following columns ( array |l|l|l|l| & Column-I & & Column-II (A) & Capacitive reactance & (i) & Will continuously increase (B) & Inductive reactance & (ii) & Will remain constant (C) & Resistance & (iii) & array l Will first decrease and then increase array (D) & Total impedance & (iv) & Will continuously decrease array )

Options

  1. A( A )-( iv ),( B )-( i ),( C )-( ii ),( D )-( iii )
  2. B(A) - (i), (B) - (iii), (C) - (iv), (D) - (ii)
  3. C( A )-( ii ),( B )-( iii ),( C )-( i ),( D )-( iv )
  4. D(A)-(i),(B)-(i v),(C)-(i i),(D)-(i i i)

Correct answer

A. ( A )-( iv ),( B )-( i ),( C )-( ii ),( D )-( iii )

Step-by-step solution

aligned & X _ C = 1 C , so X _ C 1 & ( A )-( iv ) & X _ L = L , so X _ L & ( B )-( i ) aligned And R is not a function of ( C )-( ii ) impedance Z is the minimum at resonance frequency. ( D )-( iii )
