Question

Please please please help, I have a huge physicsproject due but am a complete loss at what type of circuitsthese are 1) A circuit consists of three identical lightbulbs connectedto a battery, but their wiring scheme is unknown. When bulb C isunscrewed, all the lights turn off. When bulb A is unscrewed, theother two stay on: bulb C becomes dimmer and bulb B becomesbrighter. 2) A circuit consists of three identical lightbulbs connectedto a battery, but their wiring scheme is unknown. When bulb A isunscrewed, this causes bulb B to turn off but bulb C's intensitydoes not change. I understand the concept of complex circuits but cannot firureout which bulbs are in series, parallel, and where they are placed.Karma points will be awarded Please please please help, I have a huge physicsproject due but am a complete loss at what type of circuitsthese are 1) A circuit consists of three identical lightbulbs connectedto a battery, but their wiring scheme is unknown.

Explanation / Answer

1. for the first circuit the bulbs A and B are in parallel andbulb C is in series with that combination and in series with thebattery 2. for the second circuit A and B are in series bulb C isin parallel with that combination and parallel with thebattery so that the bulb C will glow brighter
