1 Calculations Surrounding a Circuit

There KBhHIST201BullietCh19are two ways to calculate the resistance within a circuit. In reality, they are all based on the same set of rules — but one way applies them directly and the other uses a higher-level abstraction that is often easier.

Either way, this is the are the rules that rules them all: through a resistor, the Current does NOT change, the Voltage drops.

1.1 Kirkoff's Laws

These are the basic rules of circuit calculation: KBhPHYS201KirkoffsLaws

1.2 Combining Resistors Method

Combining resistors is a generalization of the Kirkoff's Laws to makes calculating circuits easier. KBhPHYS201CombiningResistors
