Voltage Distribution in a Potential Divider Circuit

AI Thread Summary
In a potential divider circuit, moving the contact X towards point P maximizes the potential difference across the divider. However, confusion arises regarding the impact on connected bulbs, particularly lamp 1. The voltage at node P and the voltage on the slider X when at P are critical to understanding the circuit's behavior. Clarification is sought on the voltage across lamp 1 and the differences between each side of it. Understanding these voltage values is essential for solving the problem accurately.

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?

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
