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...

Problem 3:[15]) A light bulb is connected in the circuit shown in the figure with the switch S open. All the connecting leads have no appreciable resistance and the battery has no internal resistance. All resistances including the bulb have R=20 Ohms and the battery voltage is 1do Volts. (a) When the switch S is open and when it is closed, what are the effective resistances of the circuit in both cases? [5] (b) When the switch is open and...

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...
