Consider the two sub-circuits shown above. The open circuit voltage of circuit C containing ideal sources and resistors is measured at V 10 V while the current though the short circuit passing through the terminals is I, 2.5 A. For this problem, we wish to find the power supplied or consumed by circuit C when the two circuits given above are connected together. We know that the power of the 2A current source is given as Pau--30W when the two sub-circuits have not been connected. a) First, find the value of the unknown voltage source V, for the circuit on the left when Pa=-30W. When finding V, assume that the circuit on the left has not been connected to circuit C yet. b) Next, find the Thevenin Equivalent circuit for the circuit on the left. Use the value of V, that you found in part (a). c) Next, find the Thevenin Equivalent circuit for circuit C. d) Connect the two equivalent sub-circuits together to form one circuit. Evaluate this circuit to predict Top and Vop (the operating value of I and V defined above) when the two circuits are connected. e) Finally, find the signed power of circuit C.
