    Capacitor
In summary, the conversation is discussing the potential consequences of putting a large capacitor across the outlet of a house with AC. The capacitor would charge in one direction and discharge in the other, and its reactance to AC is similar to resistance in DC. By increasing the capacitance, the current could be increased and potentially blow a fuse. The necessary calculations would need to be done to determine the required capacitance.

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
 
  • #5
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?
 

1. Can I use any type of capacitor to power my home outlet?

No, not all capacitors are suitable for powering home outlets. You need to use a specific type of capacitor called a power factor correction capacitor, which is designed to handle the high voltage and current requirements of household appliances.

2. How does a capacitor power a home outlet?

A capacitor does not directly power a home outlet. It is used in conjunction with other components, such as an inverter, to convert the direct current (DC) from a power source, such as a battery, into alternating current (AC) that can be used to power household appliances.

3. What are the advantages of using a capacitor to power my home outlet?

Using a capacitor to power a home outlet can have several advantages, such as reducing electricity costs, improving power quality, and reducing strain on the power grid. It can also be used as a backup power source in case of a power outage.

4. Is it safe to use a capacitor to power my home outlet?

Yes, it is safe to use a capacitor to power a home outlet as long as it is installed and used correctly. However, it is important to follow proper safety precautions and consult with a professional electrician before attempting to set up a capacitor-based power system.

5. Can a capacitor power my entire home?

No, a single capacitor cannot power an entire home. It can only power specific outlets or appliances that are connected to it. To power an entire home, a larger and more complex capacitor-based system would be required.
