(A) For circuit 2 above, rank the bulbs in order of brightness. ( use symbols <,>,= ) (B) For circuit 3 above, rank the bulbs in order of brightness. ( use symbols <,>,= ) (C) if bulb B is removed from circuit 2, what will happen to bulbs A and C? (Choose all that apply) •A stays the same •A goes out •A gets brighter •A gets dimmer •C stays the same • C goes out • C gets brighter...
1. (10 points)In the circuit below, a. How does the brightness of the identical bulbs compare? b. Which light bulb draws the most current? c. What will happen to the brightness of bulbs A, B and C if bulb A is unscrewed? (compare to original brightness) d. What will happen to the brightness of bulbs A, B and C if A is screwed in and C is unscrewed? (compare to original brightness) Use notation such as A<B-C Scedle
Rank the bulbs in the following circuit according to their brightness, from brightest to dimmest.
(2) Five identical bulbs (numbered 1-4) are arranged as shown (a) Rank the brightness of from BRIGHTEST to DIMMEST (b) What would happen to the brightness of Bulb 1 if the wire was cut between bulbs 2 and 3? Explain 5 (c) You have 3 bulbs, some wire, and a battery. Draw two circuits: One circuit must have have all 3 bulbs be brighter than the ones in the other circuit (3) Find the the current and potential difference for...
1. A student observes the relative brightness of bulbs A and B with the switch both open and closed. She finds the following: <(6 Switch open: Bulbs A and B have same brightness. Switch closed: Bulb A is brighter than when the switch was open; Bulb B does not light at all. a. With the switch closed, does current divide and recombine at the junctions? Does it divide evenly or unevenly? Explain. b. When the switch is closed, does the...
1) What happens to the electrical flow going into and out of the battery if you add more bulbs in parallel? 2) What happens to the electrical flow going into and out of the battery if you add more bulbs in series? 3) Let's say you have three bulbs (bulb 1, bulb 2 and bulb 3) in parallel and you create "short" pathway across bulb 3, what happens to the brightness of the bulbs? 4) What happens to the brightness...
B E 6. Five identical lightbulbs are connected to a battery as shown above. a. Rank the brightness of the bulbs and explain your reasoning. b. If bulbs C and D are removed from the circuit as shown below, will the brightness of bulb A increase, decrease, or stay the same? Explain your reasoning. A c. If bulbs C and D are removed from the circuit as shown above, will the brightness of bulb B increase, decrease, or stay the...
Part A Rank the circuits illustrated according to the brightness of the identical bulbs, from brightest to dimmest. Rank from brightest to dimmest. To rank items as equivalent, overlap them. Reset Help IC A B Brightest Dlmesi P Pearson
Batterles and Bulbs-Bulb Brightness"1 Identical batteries are connected in different arrangements to the identical light bulbs Rank from brightest to least bright these items on the basis of bulb brightness. Brightest 1 2. 3. 5 Least Bright Or, all bulbs have the same brightness. Please carefully explain your reasoning I
Consider a circuit with three bulbs wired in parallel. Explain how to do each problem, include a diagram of the circuit and solve it. 1. If each bulb has resistance R and they were wired IN SERIES instead, what multiple of R is the equivalent resistance of this circuit? * 2. If you add another bulb wired in parallel, by what factor does the brightness of the others change? * 3. If each bulb has resistance R, what multiple of...
