11.1 Instantaneous and
	Average Power (2)


•	The average power, P, is the average of the instantaneous
	power over one period.


1.	P is not time dependent.

2.	When θ_v = θ_i, it is a purely


	resistive load case.

3.	When θ_v– θ_i = ±90o, it is a


	purely reactive load case.

4.	P = 0 means that the circuit

	absorbs no average power.
