SYMBOLS & DEFINITIONS
Definition
Base current: The value of the dc current into the base terminal.
Collector current: The value of the dc current into the collector terminal.
Collector-base voltage: The dc voltage between the collector and the base.
Collector-base voltage, base open: The voltage between the collector and base terminals when the emitter terminal is
open-circuited.
Collector-emitter voltage: The dc voltage between the collector and the emitter.
Collector-emitter voltage, base open: The voltage between the collector and the emitter terminals when the base
terminal is open-circuited.
Collector-supply voltage: The supply voltage applied to a circuit connected to the collector.
Emitter-base voltage, collector open: The voltage between the emitter and base terminals with the collector terminal
open-circuited.
Emitter-base voltage: The dc voltage between the emitter and the base
