New year, new post. Here I am again with a new topic that I found interesting to read after watching the videos of 3Blue1Brown on deep learning. It seems like the "Hello world!" of machine learning is making a neural network that recognizes handwritten digits, so today's post will be about that.

Equipotential lines are a way to represent that the electric potential will be the same everywhere along that line. In other words, if we take a voltmeter and start to make measurements along the equipotential line, all the values will be the same (or will differ by very small values since we don't live in a perfect world)

An electric field E is defined as F/q where F is the electric force and q is the charge. The shape of the force lines in an electric field change depending on the shape and interactions that an object goes through, by this definition it means that for a point charge such as an electron or a proton, the direction of the electric field is defined by the charge

The semester is almost finished, so I finally get a change to upload something to this blog, I'll begin with the first things we saw on the "Laboratory of electromagnetic devices" class. For this class session we were asked
