  • Question
  • For a = - 1, find the value of V2
    For a = - 1, find the value of V2 ? 0 V1 none of the above V1 = i1R1 + i2R2 i1 + ai1 = i2 V2 = i2R2


  • Options
  • A. ?
  • B. 0
  • C. V1
  • D. none of the above

  • Correct Answer


  • Explanation
    V1 = i1R1 + i2R2

    i1 + ai1 = i2

    V2 = i2R2

    For a = - 1, find the value of V2 ? 0 V1 none of the above V1 = i1R1 + i2R2 i1 + ai1 = i2 V2 = i2R2

    For a = - 1, find the value of V2 ? 0 V1 none of the above V1 = i1R1 + i2R2 i1 + ai1 = i2 V2 = i2R2

    For a = - 1, find the value of V2 ? 0 V1 none of the above V1 = i1R1 + i2R2 i1 + ai1 = i2 V2 = i2R2

    Putting a = - 1

    For a = - 1, find the value of V2 ? 0 V1 none of the above V1 = i1R1 + i2R2 i1 + ai1 = i2 V2 = i2R2 = 0 V.
