Answer the following statement(s) true (T) or false (F)
1. A network is any complex arrangement of circuit elements and often involves multiple voltage sources, and the use of Ohm’s and Kirchhoff’s laws usually suffice to solve related problems. 2. It is assumed that you can completely solve a system of simultaneous equations with multiple unknowns. 3. Under the superposition theorem, we do an analysis for each power source, and the resulting currents are then algebraically combined to determine the magnitude and direction of each current flow. 4. The superposition theorem is developed on the principle that, in a circuit with multiple power sources, we can determine just how much each power source contributes toward the branch currents. 5. Occasionally, an electronics technician is confronted with a complex network of emfs and resistors for the purpose of verifying the electrical data for only one of the resistors.
