Solution,
when the switch is open :
current throgh A will be V/R and current throght B and C will be V / (2R)
hence iA is 2 times iB and iC and iB = iC
so ranking is: A then (B and C)
B) when the switch is closed :
C will be shorted and iC is nearly zero
so iA nearly equals iB
so ranking is : A , B , C

Consider a circuit containing five identical light bulbs and
an ideal battery. Assume that the resistance of each light bulb
remains constant. Rank the bulbs (A through E) based on their
brightness.
Consider a circuit containing five identical light bulbs and an ideal battery. Assume that the resistance of each light bulb remains constant. Rank the bulbs (A through E) based on their brightness. Rank from brightest to dimmest. To rank items as equivalent, overlap them.

Rank the bulbs (A through E) based on their brightness.Rank from brightest to dimmest. To rank items as equivalent, overlap them.B. What happens to bulb C?It gets dimmer.It gets brighter.There is no change.
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...
Choose the correct answer. Please explain your answers
thank you
The three light bulbs in the circuit all have the same resistance. Given that brightness is proportional to power dissipated, the brightness of bulbs B and C together, compared with the brightness of bulb A, is Twice as much, the same, half as much? The light bulbs in the circuit are identical. When the switch is closed, 12 V 12 VF Both lamps go out The intensity of light bulb...

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...
Consider the three identical light bulbs shown in the circuit. Bulbs B and C are wired in series with each other and are wired in parallel with bulb A. When the bulbs are connected to the battery as shown, how does the brightness of each bulb compare to the others? Don't forget to write your explanation on your scratch work and upload at the end of this exam for partial credit. Bulbs B and Care equally bright, but bulb A...
