Question:
A simple circuit of the form shown in Figure 7.37 is constructed using a battery and three lightbulbs. The bulbs may have different resistances as given in the six circumstances A through F. For each situation, however, the battery in the circuit is always the same, as are the wire connections. Rank these circuits from greatest to smallest, according to the voltage across the bulb shown in red in the list. If two circuits have the same voltage associated with the selected bulb, give them the same ranking. Justify your rankings using your knowledge of the physics of such circuits.
A: Bulb 1: 10 Ω; bulb 2: 20 V; bulb 3: 30 Ω
B: Bulb 1: 10 Ω; bulb 2: 10 V; bulb 3: 20 Ω
C: Bulb 1: 10 Ω; bulb 2: 20 V; bulb 3: 10 Ω
D: Bulb 1: 10 Ω; bulb 2: 20 V; bulb 3: 30 Ω
E: Bulb 1: 10 Ω; bulb 2: 10 V; bulb 3: 20 Ω
F: Bulb 1: 10 Ω; bulb 2: 20 V; bulb 3: 10 Ω
Step by Step Answer:
To rank these circuits based on the voltage across the red bulb we need to consider the concept of s...View the full answer
