In a series L C R circuit R = 300 Ω , L = 0.9 H , C = 2 µ F , ω = 1000 r a d / s . The impedance of the circuitis

Options

  1. A500 Ω
  2. B1300 Ω
  3. C400 Ω
  4. D900 Ω

Correct answer

A. 500 Ω

Step-by-step solution

Z = R 2 + ω L - 1 ω C 2 ω L = 1000 0.9 = 900 1 ω C = 1 1000 × 2 × 10 - 6 = 500 ∴ Z = 300 2 + 900 - 500 2 Z = 500 Ω
