Nelson's Coulomb is aīrand new unit for us. So, so many Coulombs is the charge on an electron or a proton. Here, we shift 18 times and then one extra shift,ġ9 shifts to the right and so we'll write it as Now, when you write itĪs 1.6 x 10 to the power, now let's see how many, how many times we have shifted it. So we will shift thisĭecimal all the way to here. And of course, since it is so small we often like to represent this So they have the same values, but one has positive charge and the other one has negative charge. So the electron has this muchĬharge, but it's negative. Just goes to show you how small the charge on theĮlectron or the proton is. And the number of zeroes over here are 18. I can't write them all zero one six and some Let's see, we write it as 0.00, and there are so many zeros
The charge on an electron which we usually represent as e, it turns out to be so small. Of how big a Coulumb is, turns out that the charge on an electron or a proton is a very, very Named after the scientist the French Scientist, Charles Coulumb, who did a lot of work in investigating the force between these charged particles. Measure mass in kilograms and we measure height in say, meters, we measure charge in Coulombs. So the symbol for theĮlectric charge is q. In this video, we look at what the symbol and the unit for electric charge is. We call this "The Electric Force." And of course today we have discovered so many other particles that also possess this thing called less charge. Protons and electrons possess because of which they can attract and repel other protons and electrons. Electron charge = e = 4.8032x10 -10 esu = 1.Previous video we discussed what Electric Charge is.
