Is voltage drop different in parallel circuits?

Click For Summary
SUMMARY

In parallel circuits, the voltage drop across each component is equal to the voltage of the power supply, contrary to the misconception that it varies. This means that all resistors in a parallel configuration experience the same voltage drop as the source voltage. Understanding this principle is crucial for accurately calculating voltage drops and current flow in electrical circuits. The discussion highlights the importance of clear communication in explaining these concepts, particularly for those less familiar with physics.

I was under the impression that voltage drop was the same in parallel which would make it the power supply, but apparently not? Any insight would help. I know this isn't a hard a question, I'm just horrible at physics.

Can you reword this? I think I know what you're saying, but I don't think you're saying it very well.

The same in parallel compared to what? To series? No, but I don't think this is what you meant. I think you meant it's the same as the power supply voltage. Is this correct?

My apologies. Yes, the same as the power supply. And if that isn't the case, at least the same in each of the resistors. But the answer doesn't seem to be correct? I'm lost on how I should go about calculating the voltage drop with the provided information.
 
Say I pulled out what I can only assume is an ammeter, breaking the circuit there? Would current still flow?
