Which of the following indicates that a silicon NPN junction transistor is biased on?
Base-to-emitter resistance of approximately 6 ohms to 7 ohms
Base-to-emitter resistance of approximately 0.6 ohms to 0.7 ohms
Base-to-emitter voltage of approximately 6 volts to 7 volts
Base-to-emitter voltage of approximately 0.6 volts to 0.7 volts✓Respuesta correcta
Explicación
A conducting silicon PN junction settles at roughly 0.6 V to 0.7 V of forward drop, so that base-to-emitter voltage shows the transistor is biased on. Six to seven volts is ten times too high and would destroy the junction, and a resistance reading does not describe the bias state of a junction that is being driven by the circuit.
