Hi, now that you know the most accurate theory of how electron came to life, let’s get into electronics, but not quite yet. I can’t just tell you what the voltage and current are – the video would be too short. You won’t quite grasp the meaning. So when scientists were discovering electricity, they already […]
What does ion selective electrode mean? ion selective electrode. Noun 1. (chemistry, physics) ; An electrode whose potential is dependent on the concentration of a specific ion in the solution in which it is immersed.
What does electrode potential mean? electrode potential. Noun 1. (chemistry, physics) ; the potential difference of a half-reaction which occurs across a reversible cell made up of any electrode and a standard hydrogen electrode
I’m here at the National Institute for Standards and Technology, and I’m about to see some of the original kilogram standards. Is that right? Patrick: You are, you are. When were these made? Well the originals were made in the 1880s. There were 40 of them that were brethren of the International prototype kilogram and […]
