Current in terms of charge and velocity

WebQuarks have a different type of charge related to the strong nuclear force/interaction that is called color charge. Color charge has 3 values: Red, Green, Blue. These color charges have nothing to do with colors we see in the world around us. The proton has no net color charge so it has to have a quark of each of the colors. WebAboutTranscript. Drift velocity is the average velocity with which electrons 'drift' in the presence of an electric field. It's the drift velocity (or drift speed) that contributes to the electric current. In contrast, thermal velocity causes random motion resulting in collisions with metal ions. Created by Mahesh Shenoy.

WebDrift velocity is proportional to current.In a resistive material, it is also proportional to the magnitude of an external electric field. Thus Ohm's law can be explained in terms of drift velocity. The law's most elementary expression is: =, where u is drift velocity, μ is the material's electron mobility, and E is the electric field.In the MKS system, drift velocity … WebSo each electron gains kinetic energy equal to the amount of energy transferred electrically. The electron starts from rest (near enough) so the kinetic energy gained is given by ½ mv 2 where m is its mass and v is its speed. So we can say that: ½ mv 2 = eV. The mass of the electron is m = 9 × 10-31 kg. The electronic charge is e = 1.6 × 10 ... WebCurrent measures the flow of charges through an area over time.
