Homework Help Overview

The discussion revolves around a circuit problem involving a capacitor and an inductor, specifically comparing their potential energies after a certain time. The components in question are a 1.0 E -6 F capacitor charged to 10.0 micro C and a 1.0 H inductor.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants are exploring the relationship between potential energy, charge, and voltage in the context of the circuit. Questions are raised about the configuration of the circuit (series or parallel) and how that affects the analysis. Some participants express uncertainty about the connection and seek clarification on how to approach the problem based on different assumptions.

Discussion Status

The discussion is ongoing, with participants sharing their thoughts and questioning the assumptions about the circuit configuration. There is no explicit consensus on the setup, but several lines of reasoning are being explored regarding the implications of different arrangements of the components.

Contextual Notes

Participants note the lack of specific information about how the inductor and capacitor are connected, which is crucial for solving the problem. There is also mention of the potential impact of circuit configuration on the decay constant and energy calculations.

A 1.0 E -6 F capacitor has a charge of 10.0 micro C. It is connected to a 1.0 H inductor at t = 0. Compare the potential energy of the capacitor to the potential energy of the inductor at t = 10s. Which energy is greater?

Welcome to PF.

Connected how?

And what are your thoughts on it?
 
First of all thanks.

My thoughts

I know that potential energy is basically voltage across each component.
Also, C = Q / (change in V) ; C is the capacitance, Q is the charge, and V is volts.
solving for change in V and we get
V = Q / C

Am I going in the right direction?

First of all I don't know how it's connected. Is the inductor in || to the capacitor? What is the circuit?

That's all the problem says. Let's assume that it is in series then how would I approach the problem?

If it is in series then I think it matters what the rest of the circuit would be.

If it is in || then one is a short to the other isn't it?

Isn't the decay constant pretty swift?
