    Rate of dissipation of energy at resistor

    = I² R = 296

    current I² = 296/R = 296 / 300

    I = 0.9933 A.

    Impedence Z = V / I = 500 /.9933

    = 503 ohm.

    B) Let it be V

    voltage across resistance = 300 x. 9933 = 298 v

    Now 500² = 298² + V²

    V = 401 v

    C) Power factor = R / Z

    =300 / 503

    = 0.596
