THINGS YOU SHOULD KNOW Assign voltages to each node and apply KCL at nodes where voltage is unknown. The problems are voltage sources. There are three ways to deal with them: 1. Ground one end of a voltage source. Doesn’t work with multiple sources unless they are connected to each other. 2. Transform a voltage source (with a series resistance) to a current source. 3. Define a supernode which encloses the voltage source and write a second equation which is simply the voltage difference between the nodes. ABOUT MESH CURRENT (Lectures 10 Write mesh currents and apply KVL around each loop. The problems are current sources. There are three ways to deal with them: 1. A current in an external loop is no problem. It becomes the mesh current. 2. Transform a current source (with a parallel resistance) to a voltage source. 3. Define a supermesh of two meshes which enclose the current source and write a second equation which is simply the current difference between the two meshes.
