Determine the electrical mobility of charged particles, a key parameter in various scientific and engineering applications like electrophoresis, aerosol science, and microfluidics. This calculator uses the particle's charge, its radius, and the medium's dynamic viscosity to efficiently calculate how effectively a spherical particle moves through a fluid under the influence of an electric field.
Formula:
The electrical mobility (μ) of a spherical particle is determined by its charge and the drag it experiences from the medium. The formula is:
μ = q / (6πηr)
Where:
- μ = Electrical Mobility (m²/(V·s))
- q = Charge of the particle (Coulombs, C)
- η = Dynamic viscosity of the medium (Pascal-seconds, Pa·s)
- r = Radius of the particle (meters, m)
