I actually was able to figure it out. The potential ahead and behind of the bulb are the same in this case. Which means that there is no potential difference and when there is no potential difference, there can be no current because of change in V = IR. And with no current, it's impossible for...

Does this image work better for you? I'm sorry about that. When I put the bulb back in, the voltage across it is still 0V. I can see that the current doesn't even go through the wires to the 20 ohm bulb. Maybe because the potential is higher here? I know it will flow from high to low potential...

When using the voltmeter and ammeter to investigate the circuit, it was found that the batter had a current of 0.67 A, the two 30 Ω bulbs had a current of 0.17 A, and the two 10 Ω bulbs had a current of 0.50 A. In terms of voltage, each bulb had a voltage of 5 V. When the switch was closed, the...
