The region between the emitter and collector of a transistor that receives minority carriers injected from the emitter. It is the element that corresponds to the control grid of an electron tube . BASE FILM - The plastic substrate material used in magnetic tape that supports the coating. The gain of a transistor is varied by changing the bias on its base . The amount of energy available from a battery.
Battery capacity is expressed in ampere-hours .
BAUD - A measurement of speed based on the number of code elements or units per second . BAY - Part of an antenna array . BEAM - See LOBE . An electron tube in which the grids are aligned with the control grid. Special beam-forming plates are used to concentrate the electron stream into a beam.
