4. Power Consumption in Automotive Headlight Bulbs Suppose an automobile is designed with two headlights which each consume 100 W. The bulbs are powered by a 12 V electrical system. (a) Calculate the resistance of each bulb, assuming that the voltage across each bulb is 12 V and assuming that each bulb consumes 100 W. correct: (b) Suppose that the bulbs are connected incorrectly. that is, suppose they are connected in series rather than in parallel. 12 V P= 100...

A 12-volt battery is connected to two light bulbs, as drawn in
Figure 1. Light bulb 1 has resistance 3 ohms, while light bulb 2
has resistance 6 ohms. The battery has essentially no internal
resistance, and all the wires are essentially resistanceless,
too.
When a light bulb is unscrewed, no current flows through that
branch of the circuit. For instance, if light bulb 2 is unscrewed,
current flows only around the lower loop of the circuit, which
consists of...
