Recall that our methods for analysis of simplest circuits, which can be reduced to parallel and series connections, were all based on KCL, KVL, and Ohm's law. Here we start working with circuits that do not reduce to series and parallel connections. The more advanced methods for circuit analysis are also based on the same foundation – KCL, KVL, and Ohm's law . The most powerful method, applicable to any circuit, is the node voltage equations. The big idea is simple: charges are neither created nor destroyed at any node thus the algebraic sum of currents leaving the node must equal zero. Each current is calculated from Ohm's law using the given resistances between nodes and the node voltages, which are either known (in very simple circuits) or unknown (leading to a set of simultaneous equations). The second method is mesh currents. It is also powerful and – in some circuits – helps to get answers faster than node voltages. The big idea is also simple: since energy is conserved, the algebraic sum of voltage drops around any closed loop must be zero. To

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
