Section 1.6 Combining resistors (WIP)
- Two rules: 1. Current through series devices must be equal. Current can't disappear - amount going into a device must match the amount coming out of a device. Amount going into a wire must match the amount going out. (this is KCL) 2. Voltage across parallel devices must be equal. The potential difference between two nodes is constant, regardless of which way you go. (this is a correlary of KVL) Voltage dividers / resistors in series Current dividers / resistors in parallel What happens when you put a little incandescent bulb in parallel / series with a big heating element?
