Voltage Distribution in a Potential Divider Circuit

Click For Summary
SUMMARY

The discussion centers on the voltage distribution in a potential divider circuit, specifically addressing the behavior of voltage when a contact point X is moved towards point P. Participants confirm that the potential difference across the potential divider reaches its maximum when X is at P, and they explore the implications for the voltage across lamp 1. The conversation highlights the need for clarity on voltage measurements at various points in the circuit, particularly when using a 12V battery.

Homework Equations

The Attempt at a Solution


When we will move the contact X towards P, the potential difference should be maximum across the potential divider. I work out A as my answer but I think it is wrong.

Yes, that is incorrect.

True, but how does this affect the bulbs? What is the potential difference across lamp 1 when you connect X to P?

This is where my confusion is..

@cnh1995 Can you guide me further?
 
Let's say the battery is 12v.
What is the voltage at node P?
What is the voltage on the slider X when it's at P?
What is the voltage on each side of lamp 1?
What is the difference between each side of lamp 1?
