Hi, my question relates to light bulb brightness in a circuit with light bulbs connected in series and in parallel. Ill give you the question and then my argument. Q1:In this diagram light bulbs A,B, and C are all equal. Rank in order the most bright to the least bright. A1: I would argue that B and C are equal in brightness and are both greater in brightness than A because the amount of current running through B and C is equal and greater than A, and since the amount of current running through a bulb determines brightness, A must be the least bright. Q2: Suppose a wire is connected between points 1 and 2 running through bulb C. What happens to the brightness in all the bulbs A2: Bulb C would be short circuited and thus go out, but I am not sure what happens to A and B. Please help Q3: What happens to the current drawn from the battery when the wire is connected A3: The current drawn from the battery is decreased because there is no current flowing through C?? Please help Sorry for the long post but please look over my arguments and tell me if im right or wrong. THANKS!!
