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.
