Bob F Posted February 20, 2009 Report Posted February 20, 2009 In the circuit below, what happens to lamp R1 if lamp R2 goes out? Nothing Lamp R1 gets dimmer Lamp R1 gets brighter Lamp R1 goes out Quote
Bob F Posted February 20, 2009 Author Report Posted February 20, 2009 (edited) Sorry, I got the choices wrong. Please read R1 instead of R2 for the voting choices. Edited February 20, 2009 by Bob F Quote
Bob F Posted February 21, 2009 Author Report Posted February 21, 2009 It's getting too easy. Yep, all 100% correct. The other lamp will go out. A Series Circuit has only one path to ground, so electrons (current) must go through each component to get back to ground. All loads are placed in series. Therefore: 1. An open in the circuit will disable the entire circuit. 2. The voltage divides (shared) between the loads. 3. The current flow is the same throughout the circuit. 4. The resistance of each load can be different. Quote
