  1. Question 1

    Q1. Power factor of an LCR circuit is 0.8. If resistance is 100 Ω, find impedance.

    • A) 80 Ω
    • B) 125 Ω
    • C) 100 Ω
    • D) 200 Ω

    Answer: 125 Ω

    Explanation: Use power factor = R/Z, where R = 100 Ω and power factor = 0.8. So, Z = R / 0.8 = 100 / 0.8 = 125 Ω.
