A generator has a terminal voltage of 102V
when it delivers 10.3 A, and 92 V when it
delivers 31.9 A.
Calculate the emf.
Answer in units of V

  • physics -

    Ri = (102-92)/(31.9-10.3) = 0.463 Ohms,
    internal resistance.

    E = 102 + 10.3*0.463 = 107 Volts.

    Or E == 92 + 31.9*0.463 = 107 Volts.
