- 【单选题】In the short transmission line model, the relative size of the sending end voltage Vs and the receiving end voltage Vr depends on the load power factor. Which of the following is correct? Power factor = 0.8 (leading) Power factor = 1 Power factor = 0.8 (lagging) A Vs > Vr Vs < Vr Vs < Vr B Vs < Vr Vs = Vr Vs < Vr C Vs < Vr Vs = Vr Vs > Vr D Vs > Vr Vs > Vr Vs > Vr A. See item A in the problem B. See item B in the problem C. See item C in the problem D. See item D in the problem
