Trivia Friday (12072024)
An N-P-N transistor in a common emitter mode is a simple amplifier with a collector current of 0.005A. The terminal of an 8V battery is connected to the collector through a load resistance RI and to the base through Rb: The collector-emitter voltage Vce=3V, the base-emitter voltage Vbe=0.7V, and the base-emitter amplification factor βdc=100. Calculate the value of Rb.
