At modest voltages (less than 500) the electrons, that are electricity as they move, travel from atom to atom. They are a negative charge. The conductor (metal for simple example) when in the solid state (wire) has atoms that are close enough together that their outer clouds of electrons mingle rather freely. Kind of like musical chairs with 20 chairs and 30 people. The freedom to move makes it easy to push them around with either magnetism, or chemistry. Imagine a hose full of buckshot with water in it. The buck shot is atoms and the water is free electrons. The water can flow through the spaces. When we ad water to one end, water is forced out the other end (near immediately, speed of light). Current is measured in Amps. 6.24X10 to the 18power electrons passing one point in one second is one amp. One volt pushes one amp through one ohm. Jim

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
