(1) A current source of value 2cos(2t) A is used to power a string of 2W lightbulbs. If you wanted to replace this current source with a DC one, but have the same power drop, what DC current should you apply (one decimal place needed)?
(2)A voltage source of value V=120cos(4t+pi) is applied to a resistor of value 10ohms. What is the average power dissipated in the resistor (integer number needed)
(3)A square wave voltage source with a peak value of 120V has a current of value 1A rms. What is the maximum average power this source can output?
(4)A voltage source of value V=6*sqrt(2)*cos(4t+45) is applied to a network of inductors, resistors and capacitors. You measure the current to be 1*cos(4t). What is the average power dissipated in the network (integer number needed)?
