(e) The phase angle between voltage and current.
SECOND DEFINITION OF IMPULSE: It can be described as, "The change in momentum produced by the force of impulse".
The simple equation E = mc² is not usually applicable to all these types of mass and energy, except in the special case that the total additive momentum is zero for the system unde
