12th Class Physics Alternating Current / प्रत्यावर्ती धारा Question Bank MCQ - Alternating Currents

  • question_answer
    Alternating voltage (V) is represented by the equation:

    A) \[V(t)={{V}_{m}}{{e}^{\omega t}}\]              

    B) \[V(t)={{V}_{m}}\sin \,\omega t\]

    C) \[V(t)={{V}_{m}}\cot \,\omega t\]         

    D) \[V(t)={{V}_{m}}tan\,\omega t\] where \[{{V}_{m}}\] is the peak voltage

    Correct Answer: B

    Solution :

    (b) \[V(t)={{V}_{m}}\sin \,\omega t\] The equation of alternating voltage is             \[V(t)={{V}_{m}}\sin \,\omega t\]
