Abstract: The main intent and purpose of this paper is to flaunt the rudimentary and homespun idea of reactive power on electrical power systems. Electrical machines such as motors and generators require reactive power for the production of magnetic field. Transformers and transmission lines too obligatory reactive power while they bring up with resistance and inductance contend with the flow of current. The Voltage profile must be uplifted to push this power through line inductance. Suitable reactive power when not used can cause contemplative black-outs. 
Keywords: Reactive power, Voltage profile, Black-out.
