Electric Flux and Electric Flux Density

Faradays experiments showed:

Direct proportionaluty between electric flux and charge on the inner sphere. And fortunately for us the constant of proportionality depended on the units used. And thanks to our standard engineers friendly SI units we got that proportionality constant equal to 1. Giving us a simple uncomplicated equation:

THE FARADAY EXPERIMENT (overview)

The farady experiment is actually a pretty long one. So as not being in my course and beyond my historical scope. This post only covers essential edited out parts of the experiment that gave us modern definition of electric flux.

Electric Field Intensity

Consider a fixed charge Q1. Let us move a second charge say test charge Qt around the Q1. We observe that the test charge Qt experiences force everywhere around Q1. It is experiencing a force field. Force on it will be given by coulombs law as: Continue reading
