Alternating Current question

2023 · 30 Jan · Shift 1 · Q58

JEE MainPhysicsAlternating CurrentMCQ+4 / −1
In a series LR circuit with XL=R\mathrm{X_L=R}XL​=R, power factor P1. If a capacitor of capacitance C with XC=XL\mathrm{X_C=X_L}XC​=XL​ is added to the circuit the power factor becomes P2. The ratio of P1 to P2 will be :
  1. A
    1 : 2\sqrt22​
  2. B
    1 : 3
  3. C
    1 : 2
  4. D
    1 : 1
