The figure (Figure 1) shows a simplified circuit for a photographic flash unit. This circuit consists of a 9.0-V battery, a 50.0– kN resistor, a 140-µF capacitor, a flashbulb, and two switches. Initially, the capacitor is uncharged and the two switches are open. To charge the unit, switch S1 is closed; to fire the flash, switch S2 (which is connected to the camera's shutter) is closed. Part A How long does it take to charge the capacitor to 4.5 V ? Express your answer using two significant figures.

Two identical light bulbs (with identical resistances) are connected in series to a constant voltage source. If the light bulbs are instead connected in parallel to the constant voltage source, what is the ratio of the brightness of a light bulb in the parallel configuration to its former brightness when connected in series? 4 times brighter none of these 1/4 as bright 2 times brighter 1/2 as bright same brightness
Four identical bulbs, each with a filament resistance of 144 Ω, are connected to a 20-V battery as shown in the diagram below. S1, S2, and S3 represent switches. (a) If S1 and S3 are closed while S2 is open, what is the current through each bulb? bulb 1 A bulb 2 A bulb 3 A bulb 4 A
The resistance of each brake lightbulb on an automobile is 6.7 Ω. Use the fact that cars have 12-V electrical systems to compute the current that flows in each bulb if they are connected in series. (For simplicity, assume that the circuit is only composed of one brake lightbulb and the car battery.)
