Jimmy the Circuit Builder has seven circuit elements on his workbench. He is trying to build circuits that produce or dissipate specific amounts of power from specific elements. The seven elements are shown below. They include two voltage sources (4 V and 8V), two current sources (5 A and 10 A) and three resistors (31,61 and 91). Each of the sources can produce a maximum of 500W. All elements have a maximum dissipation rating of 1 kW. Jimmy's workbench has...
