Question

    A series LCR circuit has a resistor of 100 Ω. At

    resonance, the voltage across the resistor is 50 V and across the inductor is 30 V. If the angular resonance frequency is  3 × 10⁵ rad/s,  what is the inductance L?
    A 0.2 mH Correct Answer Incorrect Answer
    B 0.1 H Correct Answer Incorrect Answer
    C 0.6 mH Correct Answer Incorrect Answer
    D 0.5 mH Correct Answer Incorrect Answer

    Solution

    We are given a series LCR circuit operating at resonance . At resonance: We are given a series LCR circuit operating at resonance . At resonance: Voltage across the inductor:
