Homework Help Overview

The discussion revolves around a problem involving capacitors, specifically a scenario where a wire shorts two capacitors (2μF and 3μF) in a circuit with a 6V supply. The original poster is trying to understand the implications of this setup on the charge of the capacitors.

Discussion Character

  • Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • The original poster attempts to identify their mistake in reasoning about the charge on the 2μF capacitor, suggesting it should be zero due to the short circuit. Other participants question the validity of the provided answer options and discuss the implications of the potential across the capacitor.

Discussion Status

Participants are exploring the reasoning behind the charge distribution in the circuit. Some express agreement on the idea that the charge on the 2μF capacitor should be zero, while others question the accuracy of the book's answers. There is no explicit consensus, but a productive dialogue is occurring regarding the assumptions made in the problem.

Contextual Notes

Participants are discussing the implications of a short circuit in the context of capacitor charge, with some suggesting that the potential across the shorted capacitor is zero. The original poster's confusion stems from the options provided in the problem statement.

The Attempt at a Solution

Sorry for the unclear image .

There is a wire across the combination of 2μF and 3μF capacitors which means the two capacitors are shorted . The whole of 6V drops across the 1μF capacitor . In that case charge on the 2μF capacitor should be 0 . But this is not an option .

What is my mistake ?

I think it's a wrong answer by the book honestly.

You mean none of the options are correct ?

Do you agree there would be 0 charge on 2μF capacitor ?
 
yea because the potential across the capacitor is 0
