What is the difference between active power and reactive
power....?
Answer Posted / venkatanarayanasami
Note that this is an engineering convention, not a concept
from pure physics. When you multiply voltage by current,
the total "power" in volt*amps can be a combination of two
types of "power". 1. active power = V*I*cos(theta) and 2.
reactive power = V*I*sin(theta) where (theta) is the phase
angle between the voltage and current.
