Voltage Distribution in a Potential Divider Circuit

Click For Summary

Homework Help Overview

The discussion revolves around understanding voltage distribution in a potential divider circuit, particularly focusing on the effects of moving a contact point within the circuit on the potential difference across components, such as bulbs.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants explore the relationship between the position of the contact X and the potential difference across the potential divider. Questions arise regarding the implications of this movement on the voltage across specific components, particularly lamp 1.

Discussion Status

The discussion is active, with participants questioning the correctness of initial answers and seeking clarification on how changes in the circuit configuration affect voltage readings. Some guidance has been offered regarding specific voltage values and their implications.

Contextual Notes

Participants are working under the assumption of a 12V battery and are trying to clarify the voltage at various points in the circuit, including node P and the slider X.

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?
