While this might bring out laziness and excessive video game playing in the rest of us, Ampere discovered a natural love for knowledge, devouring as many books as he could from the family library and even memorizing pages from the encyclopedia. He also organized chemical elements by their properties in a periodic table a half century before today’s modern periodic table came into existence.Īn interesting bit about Ampere’s education – He didn’t have any formal studies! Instead, his father let him do as he pleased, learning anything.He was also the first to bring out the idea of the existence of a particle that we all widely recognize as the electron.His major discovery of demonstrating that wire carrying an electric current can either attract or repel another wire that also has a current flowing through it, without the use of physical magnets.You can thank Ampere for some pretty great stuff, including: ( Image source)Īmpere was a French Physicist and Mathematician, and also one of the founders of the science of classical electromagnetism. Under this model, it was assumed that electricity flows from positive to negative.Īndre-Marie Ampere, the self-educated man that accomplished far more than just discovering Amperes. There are two schools of thought for how current flows in a circuit Conventional Flow or Electron Flow, let’s look at both:Ĭonventional Flow – Conventional Flow was first, in a period of scientific discovery when people didn’t understand electrons and how they flowed in a circuit. Just like you need to tell yourself to keep running once you get tired, voltage is the motivating force behind current that keeps it moving.

It’s the voltage that we talked about earlier. The electric current flowing through your circuit is always measured in Amperes or Amps. Like taking steps to complete your morning run, current is the constant movement, or flow, of electricity in a circuit. This process of running and measuring the process is what Current is all about. As you run, your smartwatch measures exactly how far you went and how fast you traveled. Maybe an hour into your run and you start to hit your stride, ready to run for miles. Here’s current in motion in our bodies, who knew that electricity could be so personal? Minus the two numbers, and you get your potential difference. The positive end measures at 9V, and the negative end measures at 0V. Take a 9-volt battery, for example, if you measure the positive and negative ends, you’ll get a potential difference of 9 volts (or close to it). In an electrical circuit, voltage is measured by finding at what’s called the potential difference between two points with a multimeter.

If left alone, then the voltage remains where it is, never realizing its full potential. But like making a choice to run, you have a choice of whether to tap into that source of voltage in your outlet. Look at every unused wall outlet in your house – There is voltage buzzing in those sockets ready to do work for you. Voltage is all around just waiting for us to tap into its potential. It’s this voltage force that motivates electrons to flow in a circuit and keeps them running hour after hour. Like having the potential to move or not, voltage is stored electrical energy with the potential for movement. If you don’t decide to run this morning, then your potential will sit dormant, but if you do, then that potential will explode outward, propelling you to run for miles and energizing the rest of your day. We all have potential, and when it comes to running, the potential in question is making a choice of whether to run or sleep. This is the essence of voltage it’s all about the difference of potential. You can either stay in bed and sleep a little bit longer or get up and start moving your body. You know it’s good for you, and you’ll feel great once you get moving, but every morning you have to make a choice. You’re laying in bed, wanting just a few more hours of sleep, but knowing that it’s time for that dreaded morning run. And rather than go with yet another water analogy, we thought we’d get a little more personal, with our bodies in motion. We’ve climbed the highest peaks to find the right analogy to explain the nature of how electricity works in a circuit.

But to grasp the true essence of electricity, one must understand how to manipulate and measure voltage, current, and resistance. In our previous blog, we learned about the humble circuit, and it’s place in our world of electronics. It’s as Easy as Running – Understanding Voltage, Current, Resistance, and Ohm’s Law
