With these three concepts, just about any electrical circuit can be analyzed and understood. Granted, things get a little more complicated when you add concepts like inductance and capacitance, but KCL, KVL, and Ohm's law form the foundation of all circuit analysis. Brandon mentioned Ohm's law in his blog post on how to choose a resistor for your design, so I will only be discussing KCL and KVL.
