Resistors, capacitors and inductors are the basic passive elements of any electric circuit. Find out why resistors are so important, how we may describe and characterize them and what materials they are made off!

Coupled RLC circuits are solved as coupled harmonic oscillators. The detuning of the circuits is calculated.

The classic problem of the resistance cube is solved. In addition, variations are outlined such as the C- and RLC-Cube

The serial RLC circuit is solved for dissipation and eigenfrequencies.
