Homework Help Overview

The discussion revolves around the use of a capacitor in an AC circuit, specifically regarding its potential to power a home outlet and the implications of doing so. Participants explore the behavior of capacitors in alternating current scenarios.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants question the effects of connecting a large capacitor to a home outlet, including concerns about blowing a fuse. They discuss the charging and discharging behavior of capacitors in AC circuits and the concept of reactance as it relates to resistance.

Discussion Status

The discussion is active, with participants providing insights into the mathematical relationships governing capacitors in AC circuits. Some participants are exploring the implications of capacitor size on current and fuse ratings, while others are seeking clarification on fundamental concepts.

Contextual Notes

There is an underlying assumption that the outlet provides AC power, and participants are considering the implications of using a capacitor in this context without definitive conclusions on safety or feasibility.

Would I blow a fuse if I put a large capacitor across the outlet of my house?

We are waiting with baited breath!

Presumably, you have AC. What does the C do in a circuit?
 
charges up right? but what happens when it's in AC?
 
What does AC mean..alternating current...that means the current changes direction with time which means that..the capacitor should charge in one direction and discharge in the other
 
The capacitor has a reactance Rc to AC, which is pretty much similar to resistance in DC.

Rc = I/wC, where w = 2(pi)f. In analogy with DC, V = I*Rc => I = 2(pi)VfC, where V and I are actually the RMS values. V and f are set by the power companies, and you can't do anything about them.

By making C high, you can increase I. To blow a fuse, you need around 5 A of current. Now do the math for what C you need.

SO, when are you planning to do it?
