The voltage and current at the terminals of a network are
v=30+56cos2000t+20sin8000tV,
i=3+5cos(2000t−25∘)+sin(8000t+45∘)A.
The current is in the direction of the voltage drop across theterminals.
Part A
What is the average power at the terminals?
Express your answer to three significant figures and include theappropriate units.
Part B
What is the rms value of the voltage?
Express your answer to three significant figures and include theappropriate units.
Part C
What is the rms value of the current?
Express your answer to three significant figures and include theappropriate units.
