Alternating Current question

2022 · 30 Jun · Shift 1 · Q56

JEE MainPhysicsAlternating CurrentMCQ+4 / −1
In series RLC resonator, if the self inductance and capacitance become double, the new resonant frequency (f2) and new quality factor (Q2) will be : (f1 = original resonant frequency, Q1 = original quality factor)
  1. A
    f2=f12{f_2} = {{{f_1}} \over 2}f2​=2f1​​ and Q2=Q1{Q_2} = {Q_1}Q2​=Q1​
  2. B
    f2=f1{f_2} = {f_1}f2​=f1​ and Q2=Q1Q2{Q_2} = {{{Q_1}} \over {{Q_2}}}Q2​=Q2​Q1​​
  3. C
    f2=2f1{f_2} = 2{f_1}f2​=2f1​ and Q2=Q1{Q_2} = {Q_1}Q2​=Q1​
