specific charge
specific charge n (General Physics) physics the charge-to-mass ratio of an elementary particle specific charge
Specific charge The ratio of charge to mass expressed as e/m, of a particle. The acceleration of a particle in electromagnetic fields is proportional to its specific charge. Specific charge can be determined by measuring the velocity which the particle acquires in falling through an electric potential; by measuring the frequency of revolution in a magnetic field; or by observing the orbit of the particles in combined electric and magnetic fields. See Elementary particle specific charge[spə′sif·ik ′chärj] (electricity) The ratio of a particle's charge to its mass. |
