Answer Posted / venkat iyer

Apparent power - The power made available to us by
electricity authority for which we pay tariff.
Active power - The power that the connected load consumes
Reactive power - A nuisance power generated by the
connected load in the system itself.
All the three are vector components. Therefore in a common
man's language, active power is nothing but apparent power
delivered at a factor known as 'Power Factor'
