Humans have an intimate relationship with electricity, to the point that it's virtually impossible to separate your life from it. Sure, you can flee from the world of crisscrossing power lines and live your life completelyoff the grid, but even at the loneliest corners of the world, electric...
Basics of Household Electricity To understand how circuit breakers work, it helps to know how household electricity works. Electricity is defined by three major attributes: Voltage Current Resistance You've probably heard of low-voltage circuit breakers and medium-voltage circuit breakers, but what ...
As we've already discussed, a generator converts mechanical energy into electricity. A motor works on the same principles, but in the opposite direction -- it converts electrical energy into mechanical energy. To do this, a motor needs a special kind of magnet known as an electromagnet. In...

In science don't confound normal static electricity to ecstatic eccentricity. Here is what I found: electric charges, as they rise up your hair in contrast with a discharge, rarely leaves you up in the air ~ Ana Claudia Antunes If as an individual you love spending time in order to under...
How Electricity Works: Electricity Basics Electricity starts with electrons. If you have read How Atoms Work, you know that every atom contains one or more electrons. You also know that electrons have a negative charge. Simplest model of an atom In many materials, the electrons are tightly boun...
In this lecture we will learn what electric charge and current is and how electricity works. To understand electricity, we need to start with the atom. Matter is made of atoms. We are made of atoms. Everything in the Universe is made of atoms.
Let's take a closer look at how it works!Photo: A typical small electricity transformer supplying houses from the main power grid. Note the cooling fins (those vertical metal plates) on the four sides.Sponsored linksContents Why do we use high voltages? How does a transformer work? Step-...
Solar panels work by generating electricity using solar radiation. They’re like sandwiches made of special materials, mainly silicon and glass, with a dash of metals like boron and phosphorous. These layers work together to create solar energy in the form of electricity. When the sun’s light...
