Current flow through no resistance conductor

Click For Summary
SUMMARY

The discussion centers on the flow of electric current through a circuit with resistors and an ideal voltmeter. It is established that current will preferentially flow through paths with no resistance, effectively bypassing resistors like R1. The participant concludes that removing the voltmeter, which has infinite resistance, does not alter the current flow through R2 and R3, which are in parallel and in series with R1 and R4. This understanding is crucial for analyzing circuit behavior in electrical engineering.

Homework Statement


How does the electric current flow through this circuit?

2. The attempt at a solution
It would make sense for me to take the path where there's no resistance and skip the path with the resistance R1, but I'm not 100% sure about that.

So how does it flow? pic1 or pic2? also an explanation would be very useful.

Thanks.

Oh, i figured out now, it would be the same case if we removed the Voltmeter (since it has no resistance), in that case R2 and R3 are parallel, series with R1 and R4.
 
Presumably V represents a voltmeter. An ideal voltmeter has infinite resistance, so no current should flow through it.
