Answer / sai kiran

Question itself is wrong.
In resistive loads, the power factor is unity as there is no involvement of reactive power unlike in case of inductive or capacitive loads.

Answer / sudipt jena

Absence of reactive power.
As we know series connection of inductor or capacitor leads to phase shifting of current with certain angle and hence decreasing the power factor of the line. But unlike capacitor/inductor a resistance is a passive element, resulting unity power factor.

explain about the electrification in the Indian Railways? ie., how the power is taken and used to drive the train? explain with the block diagram??
