Therefore, on average there will be no overall motion of charge carriers in any particular direction over time. However, when an electric field is applied, each electron or hole is accelerated by the electric field. If the electron were in a vacuum, it would be accelerated to ever-increasing velocity (called ballistic transport). However, in a solid, the electron repeatedly scatters off crystal defects, phonons, impu… redbridge alternative provision schoolWhen a charged particle in a gas or liquid is acted upon by a uniform electric field, it will be accelerated until it reaches a constant drift velocity according to the formula $${\displaystyle v_{\text{d}}=\mu E,}$$ where $${\displaystyle v_{\text{d}}}$$ is the drift velocity (SI units: m/s), $${\displaystyle E}$$ is the magnitude … Visa mer Electrical mobility is the ability of charged particles (such as electrons or protons) to move through a medium in response to an electric field that is pulling them.
