Instantaneous Power
lang:""
"Instantaneous Power}, for a two-terminal element or a two-terminal circuit with terminals A and B, is the product of the voltage $$u_{AB}$$ between the terminals and the electric current i in the element or circuit: $$p =$$u_{AB} \cdot i$$, where$$u_{AB" is the line integral of the electric field strength from A to B, and where the electric current in the element or circuit is taken positive if its direction is from A to B and negative in the opposite case. For an n-terminal circuit, it is the sum of the instantaneous powers relative to the n - 1 pairs of terminals when one of the terminals is chosen as a common terminal for the pairs. For a polyphase element, it is the sum of the instantaneous powers in all phase elements of a polyphase element. For a polyphase line consisting of m line conductors and one neutral conductor, it is the sum of the m instantaneous powers expressed for each line conductor by the product of the polyphase line-to-neutral voltage and the corresponding line current.
