1) What is the relationship between line impedance and regulation?
2) What is the relationship between line impedance and losses?
3) How does poor power factor increase the cost of supplying power?
4) How would you correct poor load power factor?
5) Prove that if in a given electric power system the voltage, the active power, the power losses and the power factor are all constant, the weight of the conductor will vary proportionally to the square of the transmission distance (i.e. wαl^2).
