1) The power factor correction impedance is placed in parallel with the load. Can it be installed in series? Justify your answer.
2) What happens to the power supplied by the source before
and after power factor correction? Why, in the absence of power
factor correction, does the source need to deliver more power to
the circuit to maintain the voltage at the load? Justify your
answer in terms of reactive power, and line losses.
