Gauss' Law

Understanding Gauss' Law:

We started the day understanding about the relationships between charges and electric field. Given 3 charges at different locations, the electric field is shown as below. We also learn about the relationship between flux and charges. When we try it in the website written below, we found that as charge increases, flux also increases. This means that flux and charge are proportional. Lastly, we learned about gauss' law, which says that flux is equals to integration of Electric field multiplied by change of Area.

Faraday Cage:

Electric from the ... Is connected through a metal conductor to a faraday cage. This experiment is to show the location of the charges around the faraday cage.

Given a situation where there's a lightning storm when we are stuck in a car, we needed to find the best decision to make to avoid this lightning. Staying in the car would be the best decision because lightning would hit the metal first and the metal would be grounded.

There are strings hanging on the inside and outside of the faraday cage. We want to know where the charges are located on the faraday cage. When we activated the apparatus, only the strings on the outside are moving. This shows that the charges are only on the putside of the faraday cage.

We learned from earlier about gauss' law.  We also know that flux is charge divided by ... By equating these equations, we found that integration of electric field multiplied by change in area is equals to charge divided by ..

By using the equated equation, we cab now find the equation of electric field by itself by dividing both sides by Area, but we know that charge divided by area is sigma. Therefore, the equation of electric field is sigma divided by .., which can also tell us the equation of sigma.

The way that faraday cage works is that charges wants be at the maximum distance of each other. The maximum it can be in a faraday cage is in the most outer part of the cage. Thus, there is no charge in the inner part.
